Don't rely only on GRB Vol 2 for theory. Use it as a problem bank after mastering concepts from:
GRB Vol 2 contains several “Mock Olympiad Tests” at the end (usually 5 problems, 5 hours). Do these under strict exam conditions. Scan your answers and grade yourself ruthlessly. grb physics for competitions vol 2 pdf
When students search for the PDF, they are often frustrated by scanned copies with missing pages or blurred diagrams. This is because the physical book is notoriously dense. Consider a typical problem from GRB Vol 2, Chapter: Electromagnetic Induction: Don't rely only on GRB Vol 2 for theory
"A metallic rod of length L rotates about an axis perpendicular to a uniform magnetic field B. If the angular velocity is ω, find the induced EMF between the center and one end. Furthermore, if the resistivity varies along the length, derive the current density." "A metallic rod of length L rotates about
Most books stop at the standard (1/2)BωL^2 formula. GRB pushes you to the integration of variable resistivity. This level of depth makes the PDF version a prized possession—students want to annotate, zoom, and search for specific derivations without carrying a 1,500-page brick.
While Volume 1 covered basic lenses, Vol 2 focuses on wavefront division and amplitude division:
