What are some things I can do to prepare months in advance prior to starting pre-reqs? Hi guys, I'm basically a baby and I've been out of school for a bit.

I am hoping to return back to school later this year and begin taking pre-reqs. I'm really worried about returning back to school- my high school was not great. I would really like to do the best I can to prepare for pre-reqs since I have so much time.

What should I do? I've already started watching "Intro to Chemistry" on Khan Academy.
