For Grade 11 students preparing for the IIT-JEE, recommendations for physics reference books include Arihant publications, I.E. Irodov, and University Physics. While H.C. Verma is often suggested for its concept-based problems, some students find its theory lacking and prefer alternatives. The discussion emphasizes the importance of building intuition through problem-solving rather than merely tackling difficult problems. It is noted that H.C. Verma's problems, although not tough, are conceptually rich and essential for understanding fundamental physics. Other suggested books include D.C. Pandey and Krane, which provide a balance of theory and problem sets. The consensus highlights the value of books that challenge students to think deeply about concepts rather than relying solely on extensive solved examples.
