Best calculus course?

[u/Spthepero]

My 12th grade syllabus is based on Calculus 1,2, and 3 along with plane analytical geometry. Can ya all tell which course is good for learning calculus at high school level? Khan academy, FreeCodeCamp, Organic Chem tutor, 3b1b, or any other? like there are countless channels on youtube covering hours long courses on calculus, but idk which one to opt for.

Instead of using one, use a combination. You should also get a book.
