Review for Organic Chemistry

I am starting Organic Chemistry 1 this fall (I start next Tuesday the 19th) for college. I checked out the Organic Chemistry course on Khan Academy for a review section or a refresher to prepare for the Organic Chemistry material but I didn’t see any reviews. Do you know if Khan Academy has a chemistry review that can prepare me for Organic Chemistry or possibly add a review section if possible? There weren’t any practice problems I saw in the course. Is there anyway to add practice problems throughout the course too?
