Drop the bio class. Focus on your other classes - go to office hours, get a tutor, etc. Devote 3 hours to prep for each class period. Study in a quiet place in the library.
Aim for a B in chem and a B+/A- in AHS and Psych.
Stop thinking about pre-med for now. If that’s in the cards you’ll find a way later. For now, figure what you’re good at.
Perhaps consider taking summer classes at a community college near your home. I would recommend taking statistics and Economics in case those interest you.
