Hi guys, I have Feynman lectures, University Physics, and Irodov problems in general physics with solutions. How do I make use of these books? Firstly, I must say that university physics textbook is rather simple to go through, but I've heard that Feynman lectures are better for physics olympiads. However, will that book be outdated (in terms of being revised for errors or wordings)? I've checked online and discovered that there may be misunderstandings while reading because of how certain words are phrased. Can I rely on Feyman's Lectures then? I'm rather new in introductory physics so I may not be able to verify the errors or concepts in this book. Also, for practice, which book should I start first with? University Physics ones seems simpler but because of the time constraint I am not sure which one should I do (given that there's so many questions for each chapter) Because of this time constraint, is it wiser to just do Irodov's ones since it is slightly more difficult? If I have to do questions for practice, which questions in specific would it be best to maximize my time for the olympiad? Thanks!!
