First, welcome and don’t feel hesitant to post.
With very few exceptions, every major has more applicants than there is room for. The issue becomes how tight is it? Selective majors (or impacted) mean there’s a much higher volume of applicants so even less get admitted.
The key is to look at your chosen majors in the link above, specifically at the admitted GPA range and try to get in that range, ideally as high as possible. That makes you competitive. Then look at the admit rate. If a major has a 60% admit rate you’ll stand a much better shot than one with an 8% admit rate. That said, your GPA is king — that, and completing all the major requirements listed at assist.org. Don’t be skittish about an impacted major if you have a high GPA.
