<p>I find that precalculus is mostly just a review of everything taught in geometry and algebra. Actually algebra II was like that to me as well. Try finding a precalculus textbook online and see if you understand every concept. You might want to attempt some of the problems as well to gain experience.</p>
<p>I am trying to learn BC Calculus over the summer, but I’m fairly good at picking up math concepts and I am taking precalculus this year, so I really don’t know if you will be able to do it. But anyways, take a look at those textbooks (pretty easy to find. they’re usually the out of print ones or older editions) and see if you feel comfortable moving forward.</p>
<p>Here are a few resources I came across while planning my summer (won’t go crazy with math, but enough each day to finish the course). Note that a few go beyond AB calc and into BC calc…</p>

It covers all topics in BC and is the main site I will be using in my studies. They said that all of the video lectures should be uploaded by the end of summer.</p>
