If you are stuck, look at the solution to see the next step, then try to finish it yourself.
Once you find a PDF, cross-reference its contents. For example, if you find a PDF of the 2022 All-Russian Olympiad, search for a discussion of one of its problems on AoPS. If the problem statement in the PDF matches the one being discussed in the AoPS community, you have strong evidence that the PDF is accurate.
