Shashi Bhushan Tiwari's Problems in Physics is a relatively newer but highly respected addition to the JEE Advanced preparation landscape. The books are unapologetically focused on problem-solving — minimal theory, maximum challenge. The problems are designed to test not just concept recall but the ability to apply ideas in unfamiliar contexts.

Volume 1 covers Mechanics, Waves, and Thermodynamics, while Volume 2 handles Electromagnetism, Optics, and Modern Physics. The problems are organized by chapter and difficulty, and each problem is tagged with the concepts it tests. What makes these books special is the "un-orthodox" nature of many problems — they often combine multiple topics in unexpected ways, just like the actual JEE Advanced paper does. Ideal for students who have finished their theory preparation and want to stress-test their understanding.
