How toppers play this section
The numeracy syllabus is explicitly capped at Class 10 level — no calculus, no advanced algebra. The two blocks are basic numeracy (number systems, percentages, ratios, profit-loss, time-speed-distance) and data interpretation (reading tables/graphs/charts accurately, plus data-sufficiency questions that test whether given information is enough to answer, not the answer itself). For a non-maths background, this is usually CSAT's most learnable section with focused practice.
