Hi, so I took AP Physics C in my sophomore year when I was just taking precalculus. For context, I had never taken a physics course in my entire life prior to walking into that class… so yes, at first it did seem very overwhelming. This class was by far the most difficult class I had ever taken, however with a lot of motivation and practice I was able to handle it. I would say this class involves a lot of formula memorization and understand how/when to apply them. You’ll have to do ALOT of practice problems and really understand connections across units to be successful.
On the other hand, I am currently taking AP Biology as a junior and I’d say its much more fact-based and reading-intensive. I would say this class is in many ways similar to a AP history course since it involves a lot of memorization and analyzing. The first few chapters which deal with more molecular topics (i.e. photosynthesis/cell respiration, transcription/translation…) are kinda difficult to understand at first, but after that, the rest of course is relatively easy.
Both these classes are important if you plan on going into biochemisty and with the AP exams, you may be able to get out of some colleges classes and save money. Tin addition, both classes will serve as a very strong foundation for future studies in college, but it just depends on your interests and what type of learner you are. You’ll likely take many classes related to these subjects in college, so these classes should just serve to explore your interests before you pursue them in your higher education. Also since you are going into your senior year with a course load that is already challenging, I’d say to not overkill it… senioritis is real!! Best of luck!!
