Actually, would overload and take harder classes in 1st semester if your near top end of your universities admissions. 1. You’ll get to really test test your skills, when the price (B) is redeemable. 2. You can drop a class early if feeling overwhelmed and it wont show up . 3. Every grad school/med school/ law school likes to see a favorable progression in grades. If your starting in the front based on the type of high school you went to and how you preformed then expect others will catch up in the first year or two. If you get great grades with redo classes and then GPA fades it will be worse then having slightly lower overall GPA showing improvement.
