Do you also have any honors courses? College classes seem to be weighted a bit lower than AP classes (since they’re most often taken at community colleges). So like CollegeVine might be seeing 10 AP classes, 0 honors classes, and a bunch of community college classes (which have diminishing value over large bunches). Depending on your demographic, that could very well be below UCB. A student that has 10 APs but no honors classes (like all other ones were just regular courses) probably would have a more depressed course profile, despite having a strong pool of APs.
