My question would be regarding the differences between these textbooks. What does each textbook do well? What are each books weak chapters? Difference between old resnick and new resnick? And why do Indians fanboy/girl over Verma's textbook and should I use it? I am preparing for physics Olympiad in the US, this is my first time doing it and I am in eleventh grade, i have finished studying all the mechanics chapters in kleppner and kolenkow, and am about to proceed onto studying other topics in one or two of the above textbooks in preparation for usapho. Thank you for your time and advice, and have a great day!
