In high school my favorite resource was the Calculus (9E?) textbook by Larson. Super thorough in the explanations, there were tons of practice problems and step by step solutions on their website (no subscription needed iirc) for odd # problems.
My biggest struggle was skipping some of the basics and having to go back and re-learn after really struggling. But struggling helped in a way because then I really understood why X or Y solution didn’t work. If there’s anything i’d suggest, it’s that once you get some confidence in solving problems, try to approach new ones without looking through the entire lesson first, and that will help the actual way to solve the problem really stick. (And it’ll help you ask more focused questions!)
