The only way to secure a 99 percentile in CAT 2020 is to practice a lot. Candidates appearing for CAT 2020 need to work on their accuracy and build their aptitude in Mathematics.
Accuracy
- Solve previous years questions and sample sheets.
- Observe the pattern of the questions.
- Be careful with how you answer questions as there are negative marks.
- Leave the questions you cannot solve. It is not worth the time and effort to solve them, and more importantly you may lose marks.
- One reason why a lot of candidates lose marks is because their basics are still unclear. Dig out your 10th standard textbook and revise what you didn't understand.
- If you have the time, double check the answers.
Speed
- There are only 40 minutes to solve per section.
- Time yourself while solving sample papers. If there are questions that take more time than required, focus on such questions.
- Learn to Prioritize. Solve questions you know you can solve quickly.
- Do not focus on the questions that you are unable to solve. If you are in a crunch, drop the question and move on to the next one.
- Do not be demoralized because you could not solve a question.
- Work on your calculation speed.
- Practise a lot. This will have a huge impact on your speed.
