There are these Yale Open Courses on physics by Professor Shankar. I'd like to know if I'd be okay just watching the lectures and doing the practice problems or should do all of what I just described and also get the book Fundamentals of Physics: Mechanics, Relativity and Thermodynamics by Professor Shankar as a supplement. Thank you in advance! In addition I am at a sophormore level of understanding of mathematics but I am working towards completing Probability and statistics and Precalculus on Khan Academy. I am familiar with some physics concept but don't have the mathematical skills whatsoever to convey them in full detail [very basic understanding, high school level]. Anyway, thanks!
