NMET Mathematics 140 is actually not difficult and has little to do with Olympiad. If it is only 140, strategically, you can give up a big question, save about 10 minutes, and ensure that other questions are done seriously. Actually, it's harder than being serious. Also, don't step by step, incomplete steps will deduct points.

There are always people who say that all subjects in the college entrance examination are sea questions, which is simply nonsense. If the person who said such a thing didn't deliberately distort the facts, he didn't pass the college entrance examination, at least he didn't get high marks. You may get 120 just by asking questions, but it is definitely less than 135, and you can get more than 135. The topic of the sea is only a necessary aspect, except summing up the laws and mastering the methods.
