For clarification, are you in college (after high school graduation) now, and what class level do you intend to transfer at (i.e. will you be a sophomore (30-59 semester credits) or junior (60+ semester credits) at the time of transfer)?
The higher the class level you will transfer at, the less important your high school record (versus your college record) will be. Some colleges do not consider high school records of junior level transfers.
