Transition from High school to University

Hello /sci/

I am about to transition from high school to university and would like some reading that would help me prepare for a first year engineering or general sciences course.

Preferably chemistry or physics since I am missing a few courses in those subjects but they will let me squeak by because of my marks.

Any suggestions welcome, just not SICP.
(If you were going to suggest that get back to /prog/)

If you didn't take any AP shit on HS but are willing to give up the time needed to do well in math/sciences, how much per day would one need to study each subject?
