As a former guidance counselor, I’d say it would totally depend on what college you took the courses at in NJ, and what college you want to transfer them to. For example, Stanford will most likely not accept too many credits from, say, Camden County College. You would probably be able to get out of some lower level Bio courses if you had taken Biology 101, but it really depends on the college accepting the credits. For that, you have to visit the admissions website of the college you want to attend, or talk with an admissions/transfer officer there.
