Specifically with the AP sciences:
- AP biology does not require chemistry beyond high school chemistry; college biology may require general chemistry or organic chemistry as prerequisites.
- AP chemistry may only be seen as a semester or less of college general chemistry.
- AP physics C has single variable calculus (calculus AB) as a corequisite; college calculus-based physics is usually started a semester after first semester single variable calculus, with more advanced math courses taken concurrently (multivariable calculus is typically a corequisite of the course that includes E&M).
At some schools, use of AP credit for subject credit may be accepted if the requirement is a peripheral requirement, but students who need to go on to more advanced courses in the subject may be advised not to take the advanced placement. Students considering taking advanced placement may want to try the college’s old final exams for the courses that they are allowed to skip.
