Escapism

Sometimes, I wish I could just disappear - fade into nothingness - run free from the stress and pressure of the world around. That somehow reminds me of Seymour from FFX - something about death being a way of releasing one's troubles - but the world of Spira and ours work differently, I guess.

Expectations, competitions, events, etc etc have been rather annoying - about half my holiday is burnt on various things in school; and there still is homework (5 more Yue Du Bi Ji, CMath and AMath Worksheets, read Hamlet, Geog field study, CS differentiator etc) to do.

I read a post on Louis's blog recently. It is with regard to a certain someone, or rather a few people, who are indeed going through trying times now (and already have been for a while). I indeed admire those people; under the same circumstances I don't think I could/would be able to react to the situation as well as he (or rather they) did.

Sometimes, it makes me think; are such rants warranted? I would be inclined to go for yes; as contrary to the views of *some people*, I think rants are a good way for one to release one's angsty/sad/melancholic/whatever feelings out, and personally I believe people should have the right to control their feelings.

Speaking of which, Orwell's 1984 is a rather good book and I think it would be a worthwhile read for most readers out there.

Math Olympiads

Both Olympiads are over. I think I should be able to get maybe 20 out of 35 for senior, and like 6 out of 25 for Open. I know for Open I confirmed got 8 questions right:

the one on the inscribed circle in the 50/120/130 triangle,
the one on the PI notation for tan 1 to tan 89,
the one on the number of good sets,
the one on the 40-sided convex polygon,
the one on the f(x) - 1/2f(1/x) = log x,
the one on evaluating f(2007),
the one on awarding 1 prize to each guy
and the one on the largest value of the sum of cubes.

I am a bit pissed off for carelessly missing the question on the 7-digit natural numbers containing digits 3 or more times though - I got 9 less than the answer because I forgot the numbers 1111111, 2222222 etc. 8 questions is hopefully enough to sneak in a bronze.

Amazingly, our team got into the finals for Geog. And now I need to find 1 more team member >_>

Unfounded Questions

I went for the Inter-School NUS Geog Challenge today, with Isaac, Job, Johnny and Kev Low. I knew the paper was going to be 30 minutes, 30 questions and that, based on the papers from the previous years, I wouldn't have done too badly. I was expecting like maybe 22 or 23 out of 30.

But it was hard. I'm only sure of fifteen of the thirty questions. The real reason why it was hard was because it was RANDOM. The questions seemed to have come up from all kinds of weird sources. Here are a few examples that I knew how to do:

Which of these rivers is not found in Europe? Danube / Po / Rhine / Volta / something else that I can't remember
Which of these people did not propose a classic town planning model? Burgess / Ullman & Harris / McGee / Hoyt / none of the above
Country X is landlocked, shares a border with Thailand on the Mekong River and is rich in natural resources. What is X? Vietnam / Laos / China / India / Cambodia
Which person supported pro-natalist policies despite putting forth this theory that eventually population growth would exceed agricultural development?
And some that I couldn't:
Which of these is not a warm ocean current? Gulf Stream / North Atlantic Drift / Kuroshio Current / Canary Current / something else I can't remember
Which of these countries does the prime meridian pass through? Suriname / Spain / India / (other options I can't remember)
Which of the following is the best definition of enclave tourism?
The group question was even worse, having something to do with how we would develop Marina Bay. We had to write a report in 30 minutes and by the time we actually started, we had just 19 minutes to finish.

I still have one question I would like to ask Ms Sandra Sim when we get back to school; why wasn't Russell on the team? (I wonder HOW she selected these teams in the first place >_>)

Must post abt CmPS later.

Anagramming

I was playing solitaire scrabble at Scrabulous, and on my second game I started with this rack.

The word I saw instinctively wasn't DAWNERS, WARDENS, GNAWERS, ANSWERS, STRAWEN, WANTERS, or even YAWNERS. It was something else.

Sick, and weird.

I'll post more sometimes. It's very late.

Shining Collection (Exam Results)

The results came back and my reaction is, admittedly, mixed. I must indeed thank God for my positive results in a precious few of the papers like Additional Maths and Computer Studies - but still, what IS a positive result in the first place? I will elaborate on this later. One thing I will definitely have to thank God for will be my average of 81.2%, which though is a sizable drop from term 1, is still a good (in my opinion) result. It's much like the status quo from last year, where Rene (83 plus) and Shaun (82) beat me, and I ended up third just ahead of a clump of people with 79.xx marks (Jarrel, Juzzie, Russell and Daniel all have that kind of number).

I remember Shaun, both prior and during the exams, said he wanted to beat Rene. The thing is, that's essentially the same as saying you want to be the top student (unless he screws up but that's not likely). It's near impossible, since in 2nd Language it's an automatic drop of over 20 points; unless you can go on a dreamlike run for your other subjects, it's hard.

I have categorised the results for my papers into the good, the bad and the ugly. Here goes:

- THE GOOD -
Additional Mathematics. This was not so much of a surprise, as I knew that I would be getting quite high after Mr Chua Kock Yong did the paper review with us. However, I didn't expect to get top of the level still, so this was good.

Language Arts. My score is just below the class average. The fortunate thing was that I had Paper 2 to save my really weak Paper 1. I didn't think this was that good, but when Mr Andrew Wong pointed out that it was an improvement from my previous spamming of 14-15 mark essays, I realised that this was actually good.

Core Mathematics. The flat mark isn't very good, owing completely to Paper II (like quite a few other people, I scored 50 out of 50 on Paper I). Amazingly, though, Jarrel lost marks on Paper I due to explanation as well as carelessness. I am satisfied with barely securing my 90 marks, which only like four or five people in the level did, so it's OK.

IHS. After mis-interpreting the meaning of 'delicate', I thought I'd be lucky if I scored anything higher than 17 points (4, 6 and then 7). I guess my strong spamming of examples in the Hypothesis Based Question helped shadow some of the misinterpretation there, enabling me to get a 10 for the HBQ and hence an overall 20. I was indeed surprised.

Computer Studies. I didn't know what I'd be getting (not very confident in my essays), but then I got 116/120. I really couldn't believe this initially, though I realised that I lost 1 mark for a careless mistake when calculating in hexadecimal, and 3 marks for not leaving comments on a program I did.

- THE BAD -
Geography. I hope you don't find this too offensive, but my Question 3 screwed up my score. For Question 1, I amazingly pulled in a 23 out of 25. However, I think I used too much of the time on question 1 (60 out of the 105 minutes, probably) and hence my arguments for question 3 were relatively weak.

Chemistry. If you haven't noticed by now, when I rate myself on how I did on a paper, usually I look at where I lost the marks in addition to the absolute number itself, and that is why Chemistry ended up here. A ton of the marks were lost on embarrassing careless mistakes in Paper II.

- THE UGLY -

Physics. nice 76. Jarrel, Shaun and even Russell all trashed me here. I really had a ton of careless mistakes, like shortcircuiting the circuit in question B9, and reading batteries the wrong way round (I'm serious). Still, this is my fault, as I barely studied Physics until the day before the exam, and hence my memory of various concepts wasn't very clear.

Normal Chinese. When I took this subject, I expected to be shooting for at least 70 marks, like the likes of Russell and Juzzie. Seems like it was not to be, as I got lower than even more people, like Isaac, Bryan and DNeo. I'm probably like third lowest in class or so, possibly due to a horrendous Kou Shi (24 / 40) and Ting Li (10 / 20). I hoped to get at least a 34/50 for my Zuo Wen, and I didn't. Though my original 32 was fairly close, three and a half marks in Cuo Bie Zi took most of it away. The worst was my Paper II, where I actually FAILED (and I mean LESS THAN 50%).

Actually, the real reason for my mixed reaction would be that though I did reasonably well, there was so much more potential, especially in the subjects where I crashed.

I must blog about CmPS soon, as well as my Game Theory Principle that I used in the exams.

Fears and Passage

Tomorrow.

The end. (for now)

I'm scared.

Unlike previous occasions this time I wasn't prepared enough, and I already blew quite a number of the papers, like Physics (16 marks of 90).

I will post more sometime. busy with CMPS currently.

Examinations, Stage II

If you're not the one then why does my soul feel glad today?
If you're not the one then why does my hand fit yours this way?
If you are not mine then why does your heart return my call?
If you are not mine would I have the strength to stand at all?

I never know what the future brings
But I know you are here with me now
We'll make it through
And I hope you are the one I share my life with

I don't wanna run away but I can't take it, I don't understand
If I'm not made for you then why does my heart tell me that I am?
Is there any way that I can stay in your arms?

If I don't need you then why am I crying on my bed?
If I don't need you then why does your name resound in my head?
If you're not for me then why does this distance maim my life?
If you're not for me then why do I dream of you as my wife?

I don't know why you're so far away
But I know that this much is true
We'll make it through
And I hope you are the one I share my life with
And I wish that you could be the one I die with
And I'm praying you're the one I build my home with
I hope I love you all my life

I don't wanna run away but I can't take it, I don't understand
If I'm not made for you then why does my heart tell me that I am
Is there any way that I can stay in your arms?

'Cause I miss you, body and soul so strong that it takes my breath away
And I breathe you into my heart and pray for the strength to stand today
'Cause I love you, whether it's wrong or right
And though I can't be with you tonight
You know my heart is by your side

I don’t wanna run away but I can’t take it, I don’t understand
If I’m not made for you then why does my heart tell me that I am
Is there any way that I can stay in your arms?
Daniel Bedingfield - If You're Not The One

It's been quite a long while since a song I happen to hear on the radio when going to school struck me as much as this one. At times, I have felt this way in a less romantic and less one-dimensional sense... actually I'm not really even sure what I'm talking about here, but definitely not in the same context as the singer's assumed position. It just struck me for seemingly no reason.

The usual recap:
Language Arts II - Well... I chose the highly unpopular question 2, and wrote on Ihimaera's A Game of Cards and Narayan's A Horse and Two Goats. I couldn't do question 3 very well, the way I saw things, and question 1 - well I knew I sucked at Gordimer's The Bridegroom so I stayed away from it. Granted, I could have chosen question 1, examining Ihimaera's A Game of Cards and Achebe's The Sacrificial Egg; and that might have been the better decision. I wrote 3 3/4 sides, by far the most I've written in any Lang Arts or even Literature exam for a single 25 mark question. I think I should be able to do well enough to secure my five points for Lang Arts, but definitely NOT a six, after I got killed on Pantaeva's Siberian Dream in Paper 1.

Advanced Mathematics - Jarrel, Shaun and I all already lost one mark apiece =(
Jarrel and Shaun made a *stupid mistake* of not giving the last answer in terms of PI
And I realised I made a horrible blunder when I, in a stupid brain fart, wrote:
d^2y/dx^2 = 3.60 (3sf) > 0. Hence the point is a maximum point.
And THAT was AFTER I already wrote 'maximum point' for the other one. 1 mark gone =(
At least I found a very careless mistake in an earlier part of the question, with like 1 minute and 30 seconds on the clock. This was on question 9.
2 sin x + 3 cos x = 0
hence 2 sin x = 3 cos x
Other than that, it was OK except for question 10, which I know Daniel lost 10-11 marks on. I wonder who set that question; my solution was unelegant and involved similar triangles =(.

With regard to the other papers, there hasn't been much feedback, though Bryan did tell me that according to Mr Jason Chan, we "sucked" at the Physics paper (presumably paper2, since paper1 is computer-marked). Well, it's not like we didn't do badly last year (my 73 was second in level last year, but this time 80 should be possible); and also our memories of concepts like Specific Heat Capacity and Refraction would probably be blurred, UNLESS you're a mugger.

They're mostly over. 2 last ones to go through, Chinese II and Comp Studies. I'll be going for rather high scores in both; Chinese is Normal Chinese, and Comp Studies is well... a type of Maths/Humanities subject, amazingly. You can't really study for Chinese (whether I or II), and Comp Studies shouldn't be too difficult since some of the topics don't need to be studied (Base Arithmetic, 2-Complement Testing, Logic Gates, basic Java Programming) - it's more like merely mugging the Systems Development Life Cycle.

Examinations, Stage I

It's rather unusual for one to begin a blog in the midst of the exams, but well, I guess I did. Tomorrow's papers are Lang Arts II and Additional Mathematics; and already a sense of dread fills me - why do I have to face these two papers on the same day, of all things? (Granted, several combinations, like Geography plus Chemistry would be MUCH worse, but this is already bad.)

You might wonder, why? It's not like these are mug-heavy subjects. The real reason is because by the day before, whatever you are going to do, it's not like it is going to make much of a difference. If you are well-prepared for both of them, fine. I managed to do reasonably well (or so I hope) for Chemistry today even though I didn't study that much. While I would say I am prepared for A Math, Lang Arts II looks... sinister, in its own way.

So far, the exams have been tough but doable. There hasn't been a paper other than C Maths Paper I where the whole paper was a breeze; and even then, I was unsure of a few questions in C Maths Paper I. A subject-by-subject rundown, up to this point:

Language Arts Paper I - The text for the Written Commentary was rather nasty, though by what Mr Andrew Wong had said in class in its own way I had a hint of what was coming. The text essentially had to deal with a young girl in Soviet Russia attempting to come to terms with her own identity. I can't remember the title of the source, but I do remember that it is an autobiography by Irina Pantaeva. I decided the theme was actually the importance of maintaining one's individual identity, which was OK, but I had problems finding literary devices (normally, it's the other way round; see devices but no theme). Hence, I really do not expect much for this paper.

Introduction to Human Societies - This was weird. Initially, Jarrel and a few others pointed out the "wrong" spelling of "glocalisation" when looking at the questions while checking the paper; but after reading the article, we found that it wasn't an error - "glocalisation" is a portmanteau of "global" and "local". Questions (a) and (b) were fairly easy, me having mugged Terrorism and remembering the quote "Terrorists are like sharks". However, question (c) was rather tough, as I only realised after the paper that the word "delicate" has several meanings, and the one most appropriate to the context would actually mean needing tactful management rather than what I wrote on, that being easily destroyed or broken. I will probably get a decent score, but nothing good.

Physics I and II - The first paper for Physics was easy. The second paper was tough, though, as I probably would have lost at least fifteen marks added up across the paper. I would have lost 1 mark on the question with the non-perpendicular moment, about 2 or 3 on the question asking us to calculate the temperature of tea, and 2 more on drawing magnetic field lines in the wrong direction. All was still reasonably well until I hit question B9, which featured the electric shell thing. I will probably lose like 5 or 6 marks out of 10 on this question, because my circuit diagram is wrong, and for the last question I wrote that the wire is not suitable, when Jarrel said that it was. In Question B10, I applied something I learnt from game theory, actually.

Say you have a question that goes like this - A and B are calcium salts. A is soluble in water while B is not. Give possible identities of A and B. Of course, this question is easy - an acceptable answer might be that A is calcium nitrate and B is calcium carbonate. However, if I didn't know anything about solubility, I might simply write this: A is calcium carbonate. B is calcium carbonate.

In this case, I will secure myself one confirmed point, as the two are mutually exclusive for the salts that we have learned. That is what I did for the last question in this paper. Knowing that for some reason, I always seemed to have problems applying Fleming's left-hand rule, I decided just to say that the side AB goes up and that ABCD moves in a counterclockwise direction. (If you think about it, it's sort-of similar to the first example given). Hence, though it's plus 1, it's also minus 1. I basically chose to take 1 point rather than going for a 2 or 0 situation. Adding in careless mistakes, that works out to about 15 marks gone.

Geography - This paper was fairly easy. I wrote very long answers; a total of 9 sides were churned out, because the questions were largely cliched. For example, a 10-mark essay question asked us to basically evaluate how well Singapore has coped with her urban problems. For muggers like me, this question would not be difficult as we would regurgitate a long list of points and get the 10-mark credit. Hopefully, if things go well, I can actually look at scoring more than 85 percent for this paper, which will let me get an IB score of 7 points.

Respite for a short while, then... ...

Core Mathematics I and II - The unusual duality of Core Mathematics was revealed through these papers. Paper I appeared easy, with some people like, notably, Jarrel, finishing in about 20 out of the 60 minutes allocated for it. I also found Paper I relatively easy, as I said earlier. However, Paper II brought much more to the table. Though it was a difficult paper, I must admit that it was actually very well-set. The first and second questions appeared fairly simple; as in, it was essentially tedious work employing concepts learnt in Circle Theorem and Vectors. Question 3, on Logarithms and Exponents, was a rather unusual question; the first and second parts were fairly methodical question, but the third part had an interesting bit on "explain what the calculation means". I was quite surprised a lot of people had problems with this question; in fact, I was quite surprised that I had to think for a few minutes before figuring out what it meant. This could go to show that exams indeed contribute to one's stress, and consequently, detract from one's ability to think clearly.

Question 4, on Loci, for some reason was easy for most people; but I found it extremely difficult. I forgot how to construct the locus of an obtuse angle between two points; since I kept thinking; angle at centre = 2 x angle at circumference; if angle circumference was 105 degrees then how do you draw it (as in, it is possible to draw a 210 degree angle, but not by the triangular method that we were taught.

Finally, question 5 was rather nasty as both formulas for x and y were indeed tricky to work out. The formula for x was, surprisingly, cubic; that for y was a quadratic obtained by substitution of (n-1) in the x formula - and all that for 2 marks. The rest of the question was based on well, common sense.

Chinese Paper I - This paper was enjoyable, however I do not think I will be doing very well as the ideas I put forth when writing about a girl meeting someone in a chatroom over the Internet and deciding to meet are well... at best, controversial. I think I will just leave it at that. Ying Yong Wen was fairly standard and hopefully the teachers will like my Zuo Wen.

Chinese Paper III (Listening) - I never liked Listening Comprehension tests. The speakers combined with the quiet little noises of the people around you can indeed be distracting at times. Furthermore, I know I am not a person who can think that rapidly on-the-fly; and that skill seems to be really needed in Listening Comprehension just to keep up with the passage. More likely than not, howver, it's because it is in Chinese, making two steps necessary - translation to English, then and only then comprehension.

Chemistry I and II - Chem was admittedly easier than Physics. As again, I used the game theory concept as mentioned earlier because I wasn't sure whether slag or iron would fall on top; however, I went for a 1.5 or 0.5 strategy, rather than fixed 1 or the 2 or 0 strategy. I better go now, the mug awaits; I have to go and really start working on Language Arts, lest I fail tomorrow. With paper I possibly doomed, there isn't much of a way out now.

Bye.
