I am about to complete my High school. Typically, I study text books of science but it takes a lot of time to understand the concept resulting less time to do questions and due to which I get low marks(not having English as my native language is also a factor). How should I start, please guide me from basic to advance level.
Well, one of the best ways is to enroll in a full time University course but of course that is a lot of commitment. If you don't want to do that then I would suggest looking for University lectures on YouTube. Here is a full quantum mechanics module by MIT, it doesn't get much better than that! Don't start with that module though. Universities' websites will have a list of the modules that they teach and use that as a guide for what you should learn first. Try to find problem sheets online as well so that you're constantly practicing the skills you learn.
