If you are qualified and approved for AP chem or APhys1 (based on math you are not ready for APphys C yet), it is fine to take those with APBio if you love science and have a high GPA etc. APES or ACPS is also fine. This all varies by school. At the ones I know well, APBio is by far easier than APPhysC (which is somewhat easier than APChem), and APBio can be slightly easier than APPhys1 (which is always taught at a challenging level around here) So ask your teachers and your counselor for their recommendation. Even my non-stem kid took 2 lab sciences (only 1 was AP, and was Chem) in 10th and my STEM kid took 2 AP sciences in 10th (And APCalc) and did well/As/5s etc. But that was a path her teachers recommended for her midway through 9th grade, due to her qualifications and record. My point is context of the school matters a lot, so ask. There is no need to over-challenge yourself this early.
