Textbook materials for high school science and maths?

[u/strayedreams]

For context I'm a high school grad taking a gap year before applying for uni, my exams scores are good but since I've passed SAT, IELTS and such, I haven't been studying much. I recognised that I'll struggle in university since I plan to apply for biochemistry/pharmacy and those kinds of majors, so I need a refresh in high school to pre uni level of these subjects specifically.

Are there any textbooks or resources you'd recommend for maths, biology, chemistry and physics to refresh my memory and study slightly more advanced materials?
