lol SJChO, not very hard, except for last qns, basically it asked what the 2005 nobel prize for chemistry was given out for.... zzzz
reminds me of this qns from NYP Astro competition:

anyway i didn't answer that qns because 1/2 is deducted for every wrong answer(2 marks for correct ans), but HJ did, and he said that the probability is such that its worth it. Turns out that he's right, sort of. the expectancy per question(how much on average you gain/lose per question) is +0.125marks. Dotz, tat means that by true random guessing, you'll get around 6.25, lolol. (Paper have 50 MCQ and 4 options per MCQ)
