For tutoring high school students in physics, a comprehensive source of problems is essential. Irodov's Problems in General Physics is noted for its extensive collection of around 2000 problems across various topics, including mechanics, thermodynamics, electrodynamics, oscillations, optics, and atomic physics. However, it is considered quite challenging, making it less suitable for students needing more standard textbook problems. The discussion emphasizes the need for resources that provide a balance of difficulty, focusing on more accessible problems to effectively support junior and senior students in their studies.
