CAT does not have a formally defined syllabus, but it broadly tests aptitude and analytical skills. VARC includes Reading Comprehension passages, para jumbles, para summaries, odd sentence out, and grammar-based questions. DILR covers data interpretation sets based on tables, charts, graphs, caselets, as well as logical reasoning topics like arrangements, puzzles, sequences, and games. Quantitative Ability includes arithmetic (percentages, ratios, profit and loss, time and work), algebra (linear and quadratic equations), geometry, mensuration, number systems, and modern math (permutations, combinations, probability).
