^ @thisiscarcar The suggestion above to have a fall-back plan is excellent IMO. What you have to ask yourself is this - are you willing to spend 4-5 hours per week over the summer in Chemistry self-study to prepare yourself for the rigors of AP Chem? If so, then Khan Academy awaits: https://www.khanacademy.org/science/ap-chemistry If this doesn’t sound like your idea of a fun summer, then this plan is probably not wise.
