  PDF Resources

  1. The "No Peeking" Rule: Before looking at the solutions, attempt each problem for at least 30 minutes. Russian Olympiad training emphasizes struggle over speed.
  2. Solution Autopsy: After solving (or giving up), read the verified solution. Compare your approach. Where did the verified solution use a clever observation? This is your learning moment.
  3. The Re-solve: Close the PDF. Re-solve the problem from scratch using the new method. If you can’t, you haven’t learned it.
  4. Categorize: Create a note: “Problems solved using the extremal principle” or “Invariant: coloring mod 2.” Verified PDFs often have thematic indexes.
