Will it really hurt admission chances if I get pretty good grades but low AP scores?
Don’t submit anything less than three. Depending on the school, I would be careful,of sending threes too.
If you have all A’s in the classes and all 2’s on the exams, it will smack of grade inflation. If you have one bad score, it will not matter, but as stated above, I would not list any score less than a 3.
OP has asked about tippy tops and maybe stating a potential major based on an easier admit. OP, Im not sure you get the whole picture. Nor what you mean by “pretty good grades.”
Everything should add up in the right ways. Rigor, grades, activities, and your thinking. Yes, not reporting can be a liability. Reporting low scores, same. You need to learn what your targets expect and how you match. Or not. The competition will be tough. Have great safeties.
