If you want to narrow down your study preparation, let me know , which specific physics topics you find hardest (e.g., mechanics, thermodynamics, E&M), or which competition you are preparing for. I can point you toward the exact types of problem sets that will benefit you most. Share public link

[Phase 1: Foundations] -> Solve Irodov / Krotov basic sections [Phase 2: Intermediate] -> Tackle Moscow Physics Olympiad Problems [Phase 3: Advanced] -> Attempt All-Russian Final Stage PDFs

The is widely considered one of the most difficult and prestigious national physics competitions in the world. Its problems are known for requiring deep conceptual insight and creative mathematical applications rather than just procedural knowledge.

: Community-uploaded documents often compile multi-year sets, such as the Russian Physics Olympiads 2005-2017 Structure and Level of Difficulty

by I.E. Irodov. A staple for any competitive physics student worldwide, containing excellent foundational training.

Non-trivial heat engine cycles with variable heat capacities. Phase transitions and surface tension phenomena. Statistical mechanics principles applied to ideal gases. 3. Electrodynamics

Because of copyright and language barriers, finding these problems cleanly translated into English PDFs can be a bit scattered. Here are the best sources and strategies to compile your PDF library:

Finding high-quality, archived, and translated problems is key for international students. Here are the best sources:

While many original archives are in Russian, extensive efforts by the international physics community have made translated versions widely available. Look for these essential books and digital archives: Classic Books (Available in PDF/Print)

: Often cited as the definitive resource for sharpening skills for top-tier competitions. A complete English translation is available online Shaskol’skaya and El’tsin : This classic collection of Selected Problems in Physics
