math
just came back from hkg and had the same test. very hard i must say. finished only 15 out of 33. had to gues only 2 of the 15q's. the other people finished more but guessed also a lot more answers. i got hired, not sure they did.
it is all about the answers and the amount. i dont think it is wise to rush through them and guess your way through. although you may have more answers on paper!
Take your time, thats the only way to answer them right.
but if you see a question you dont understand at all, which doesn't make sence, move on. Don't waste any time looking at them!
good luck!
