Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 40-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

What this tells you: course of action

  • Against the average: this paper asked more than usual on Triangles (11% against 4% on average) and Time, Speed & Distance (11% against 5% on average); it had nothing on Percentage, Inequalities & Modulus and Permutations & Combinations, which appear in most CAT papers.
  • This paper leaned on Time, Speed & Distance, Triangles and Algebra. Across all 24 papers the most frequent topics are Progressions & Series, Logarithms, Averages and Percentage; start your preparation there.
  • By area, Arithmetic is 41% of CAT quant, Algebra 33%, Geometry & Mensuration 15%. Split your study sessions in roughly that proportion instead of equally.
  • Trend: Factors & Divisibility has grown in 2023–25 compared with 2017–22. Weight your revision toward the recent pattern.
  • Leave for last: Boat & Stream Problems, Races & Games Problems, Number System and Calendar & Clock. They are rare across all 24 papers, so a quick revision is enough.

How to revise CAT QA previous-year questions

  • In log equations, confirm the base is positive and not one, and every argument is positive, before accepting a root.
  • In ratio-change problems, anchor on the quantity that stays fixed, such as the total coins.
  • Sketch each geometry figure and use the triangle's area to link its altitudes.
