Did I make a mistake?

You can catch up by taking biology over the summer if your school offers it, chemistry honors 10th, ap physics1 in 11th, and either AP Bio or AP chem in 12th. That would 100% appropriate for a future STEM major.

With the caveat that the OP, based on another thread, is also looking to accelerate in math. Jamming too much acceleration over the summer will likely result in a poor foundation for the future. And none of us know the OPs abilities.
