Will taking a class in community college that I already took in high school hurt my transfer admission chances?

There are many “good” four year universities.

Are you taking it for an easy A or you feel like you need the re-review.

I don’t believe it will impact your transfer - but it might not meet a transfer requirement so it might be a class not utilized in the admission process, depending upon the school.. But if you feel you need it as a basis to move up in math, it’d be smart to retake.

Good luck
