2 sets if very difficult paper , otherwise 2.5 to 3 sets

3-4 sets should be enough and more so depends on questions per set in any particular year. The most important habit in LRDI is giving yourself 12 to 15 minutes of unassisted struggle on paper before looking at any solution. Start with standard 2D matrix arrangements and grouping caselets to build structured table habits before attempting hybrid modern puzzles.
