After you’re done with your GED and remedial classes at CC (you can take your time), your “first, real, transferring-is-at-hand” classes would likely include, over your first two semesters:
2 English classes (composition, communication, rhetorics, Freshman Seminar…)
2 Calculus classes (regular or Honors - Honors may ask you to write proofs)
2 General Physics classes (") + labs
1 class in History (some colleges require it)
1 class in Philosophy or Ethics ( more important for colleges with a strong core curriculum)
1 class in Art or Art History (some colleges require it + relevant to your future major)
1 class in economics, psychology, political science, sociology, or American Studies
Your second year of “getting ready to transfer”, you’d have 2 Math, 2 Physics + labs, 2 other science classes + labs, 1 class in a social science, probably 1 or 2 art classes (due to your future major), and the rest up to you.
In order to make that more doable, you could potentially take 4 classes each semester, and 2 classes in the summer (via the summer session).
If you follow something general like the first-year schedule above, you should cover everything even the colleges with the strongest core curriculum would want.
