I don’t have any words of good advice for the OP. Not sure what else can be done except to just do really well the rest of the way and hope for the best.
However, this is a thread that others can take note of who attend Berkeley in the future…if you get a good qualifying score on your Calculus AP tests, much of the time you want to take the credit and don’t look back. To review, a 3+ on Calc AB or a 3 or 4 on Calc BC lets you skip out of Math 1A, and a 5 on your Calc BC allows you to skip out of both Math 1A and 1B. Both classes are more-or-less weeder classes.
