The Feynman Lectures on Physics (free online)
The complete three-volume classic, free and legal online. Excellent for building physical intuition beyond the school syllabus.
Intensive training with the country's best — where teams are forged.
A residential or online training camp (or series of camps) for selected students. Instruction focuses on olympiad problem solving and experimental skills. [TO VERIFY — does Nepal run a national training camp, and for how long?]
When: Typically [TO VERIFY — months and duration] before the international round.
Full international-olympiad syllabus: deeper mechanics (Lagrange/Hamilton at a basic level), electromagnetism with vector calculus, thermodynamics and statistical ideas, modern physics, and the experimental syllabus.
The complete three-volume classic, free and legal online. Excellent for building physical intuition beyond the school syllabus.
A classic collection of hard problems. Try it after finishing a university-level textbook.
Multi-round online contest with beautiful, hard problems. Archive rounds are excellent national-camp practice.
Theory and lab papers from past international olympiads, with marking schemes where published. The single best indicator of final-round style.
A practical primer on uncertainty, significant figures, graph linearisation and how to write a lab report that earns marks.
Free computer-algebra system for checking long derivations. Learn it after your algebra is solid — it is a check, not a crutch.
