I avoided all the arts-based courses at university because I knew it wasn't my strong point. Surely it makes sense to work in a field you're good at. P.S. really? I know five people who do.

I have no problem with the probability of a point in a continuous random variable being 0. :D

Some infinities are bigger than others. It's a great topic in maths and philosophy, and there's a myth that trying to grapple with infinity sent Cantor mad. I agree with the 0/1 argument.

There's always minus sign errors, and the fact that the Extension 2 exam is designed to be a time trial. Not that I expect people to get full marks, but I would expect students on top of their game in Ext2 maths to get over 100 marks raw.

I'm just pointing out that if there are students achieving below 40% raw marks in that exam, perhaps the school shouldn't have entered them in that course in the first place. Particularly not when the exam was well below par for a Extension 1 exam. There was no binomial theorem (unless you count...

You misread my post. The Extension 1 exam was such a joke that if someone gets under 40%, I can only wonder why they were in Extension 1 in the first place. (Also, if you look at the scaling reports for Ext 1 before 2001, they push the average up as well.) I don't want to sound harsh. I'm just...

I can't help but wonder what the hell were you doing Ext1 maths for if you got under 40% in that exam... Look, seriously, best of luck for the other exams - I hope you cane the other subjects so your Ext1 doesn't have to count.

It's always depressing when an exam completely ignores one of the more challenging topics in the syllabus. Predictably enough, Question 7 was projectile motion and Question 6 was simple harmonic motion. The entire examination was much too easy.

The exam was a pathetic excuse for a Extension 2 exam. Even questions 7 and 8 were not challenging. I'm going to be waiting very impatiently for the final results from this exam - I'm inclined to say that people who score under 50% should not be doing this level of mathematics.

Stewmazza, that's only half the story. Scaling tends to have one of two effects: * the mean tends to increase (although sometimes not) * the standard deviation is adjusted to even out the state for the difficulty level of the subject being studied Even the top students tend to get boosted...
