  1. Understanding topics and concepts
  2. Practicing sample questions and mock tests

CAT Maths questions are calculation intensive and even if you have studied it till graduation, you need to have complete clarity of concepts and theorems. Once there is complete conceptual clarity, start solving sample questions to improve efficiency in application of formulae for 100 per cent accuracy in solving. CAT algebra questions and CAT geometry questions are usually of high difficulty level and require practice. 

Given below are a few sample questions of CAT Quantitative Aptitude with solutions. Attempt these questions and check your preparation level for CAT exam and other MBA entrance exams.
