What should be an ideal overall score to get 95+ percentile? (can you tell me what was the score for 95+ percentile in 2020) ?

depends on the difficulty level of the exam

This year it could be around 72

i guess this time itll be more , somewhere around 80,coz this time people know the range of questions coming.so ya im guessing 80-85 should be safe score for 95

Last year 95 percentile was 76 marks.

For 80+ percentile how much we need to score?????

In CAT 2020
Score of 76 out of 228 was required to 95 percentile .

70 to 80 marks
