i am scoring 60-75 in mock test. how much percentile should i expect in actual cat?

Same with me

72 marks would fetch somewhere around 90%ile

just don't take a lot of stress,keep an option in the back of your mind that if not cat then what,this will help u relax in the exam and when u relax u should be able to get at least 3 more questions(+10 marks) correct than what u do in mocks.Don"t think about all this kitne marks pe kitna percentile.I am sure u would have thought about this 100 times already in your head which just adds to the pressure.Try to be as mentally healthy as possible in these last few days and have your sole concentration on impleting your strategy on exam day

Thank you so much guys for boosting my confidence. thanks @Froco.

Don't stop with Mock scores. Keep mock scores as practice material. Mock -> Analyse -> Mock again (keep this in repeat mode). Rewise all your concepts. Never miss an easy question in CAT which had a huge impact on your score. Gauge LOD -> Fix attempt -> with Max accuracy will fetch you 90% easily in CAT. Keep in mind, CAT never fails to surprise. Always ready for that surprise element on D-day.On D-day EQ matters a lot than an IQ. Best of luck.
