Okay James, you are right;
The OP, you are a Chinese student, ain't you? And you are asking what major you'd choose, in some Chinese school, right?
Moreover, this is an odd question, you know how many kids as old as you are going to enter a college? You didn't mention one word about your interests, your personality, your strong subjects, your and so forth and you even didn't tell us you were a natural/humanistic science student, you just asked 'what I should do'. Well, the only tip I can come up with is that logic major maybe is not very appropriate for you.
