: Heat transfer, specific heat capacity, and phase changes (melting/boiling).
: This is the most comprehensive repository. You can filter by the year 2017, Grade 8, and the "Municipal stage" (Муниципальный этап) to download PDFs of both the problems and the official marking criteria.
: Average speed, relative motion, and graphs of movement. Simple machines : Levers and blocks. Step-by-Step for Self-Study
: Municipal solutions often use a "10-point scale" per problem, where points are awarded for each logical step (e.g., 2 points for the correct formula, 3 points for the calculation).
: If a solution is unclear, search for the specific problem name on the CPMK Video Archive where experts explain the "traps" in each task.
: Specifically for Moscow students, this site provides a table with tasks and text solutions for the 2017/18 academic year.
