I have had around 2 year gap after finishing high school. The last 2 years of high school (11th and 12th grade where calculus, coordinate geometry, straight lines, circles, vectors, functions, quadratics, polynomials, probability, permutation etc. are taught here) , I barely studied and some how passed the exams through memorization. I have started to go to a university which is pretty much meant for those who could not get into a good university and it's almost the same like high school. Things are being taught via rote memorization and such. Can I get some book recommendations for learning the math/physics of high school to be able to understand the ocw courses online. As I said, I barely have any basic knowledge now of the previous math I studied since mostly I memorized. My dream is to get into robotics. I do not know if I am posting on the right forum and if this post is wrong in any way, please do tell me what was wrong.
