Multiple Choice: What is Q3 doing there? Q10 was a bit too easy for MX2 Q10 I think. A 2 unit student could have worked that one out. Overall, MC much easier than other years. Question 11: (b) (iii) could have had cleaner results. I see no reason why the argument of w had to be...

Good luck all for the exam tomorrow! Just a fun little thing I compiled and add to every year. Before 2013, iterative methods (which has never been asked in the last Q) was untouched. It then appeared as the last question of the 2013 paper. I wonder what sort of trickery BOSTES has in store...

Hi all, I'd like to wish all students doing either Extension Two or Advanced good luck for tomorrow's paper. I am sure that MX2 will have a couple of surprises in it. Remember to always try to make connections to the previous part, even if they do not explicitly say "Hence" or "Deduce"...

Hi all, We've finally finished all the marking and have your results. Much fewer people attempted the paper this year compared to last year, since last year many Extension 2 students were encouraged to also sit the paper, so please don't be too discouraged when comparing them. Thank...
