Doolie here. Had straight A's / was at top of my class at a very challenging high school. I validated a handful of classes.
First semester will be different for everyone. I primarily struggled with burn-out from high school. I had a schedule similar to most 3-degs and got C's for the first time in my life. The stress is real. This spring, I figured out how to balance being a Doolie, IC, and double major. Got majority A's a few B's, and got on the Superintendent's List.
Regardless of how the first semester goes, comeback is possible. Sometimes you have to take a few steps back before moving forward.
