How to use these papers
The last digit of the paper number is the variant: Cambridge sets two or three versions of each paper per session for different time zones, so variants 1, 2 and 3 are all fair practice. Do a paper under time, then mark it against the scheme, and revisit the syllabus point behind every mark you lost. The February/March series has fewer variants than the other two sessions, so those entries list fewer rows per paper.
