For revision, choose a manageable section and attempt it before consulting the matching markscheme. Keep a short error log separating knowledge gaps, method choices and unclear explanation. Compare the paper number, level and examination zone before pairing files. Older papers can be useful practice, but their topic coverage and format may differ from the course you are taking now.
