Nah, in a top 10 school, the top 10-15 all know how to do the last questions, trust me, it's the silly mistakes that kill you. The difference between coming 1st and 5th in our school is whether you forgot to add the minus in front of the fraction or something, not because of being unable to do the last question. I don't believe in that natural gift crap, those who struggle and fail are those that didn't study the previous years and hold no basic skills in maths. If you are an above average student, if you study hard, you can easily enter the top 5. The top ten in the state are pretty much on equal levels, what differentiates them from the rest of the state is not only being smart but having consistency.
