To me, the classes that deserve to get credits in college anywhere and to advance to any next level are the 2 English APs, Lang and Lit. Getting 5s on both is incredibly hard especially since you can’t cram for those tests. Those were the two that my kid jumped for joy in getting a 5 since he never ever again has to take a pure writing class on topics he has no interest in :))
For Calc BC the way the test is graded (I think) you can be very strong on AB and middling on C and still get a 5. At least that was my kid’s experience.
