I am still a bit confused about how exactly ap scores work…So after i send them through college board, do ap score help me opt out of specific classes or help me register for some complex high level classes? I am trying to transfer schools but the school I am trying to transfer to (Cornell CALS) hs specific courses I am supposed to take including multivariable calc which I am not sure I can take here in my school (SUNY Binghamton) with my 3 on Ap calc BC. Also how does taking classes in the summer work?
You need to check the Cornell website to find out what your AP scores are good for.
If you need to take a specific class, you need to ask Cornell if the summer class you found is the right one.
