I have 89.5% in 10th and 93.5 in inter and 69.01 in graduation,what minimum percentile do I need to get a cal from iim's(general category)

You have got decent enough marks and academics so your score can be bit relaxed.
Minimum of 99.5 percentile is what is suggested to be in safe side to get a call.

Also your GDPI scores will be very important which can make or break your admissions into IIMs.

In the last lap of CAT, it is not advised to start off with new concepts as it can be dangerous. you can rather focus on your weak areas by analysis on where you consume alot of time, focus on mock papers you have attempted, focus on questions where you are finding approach to be difficult. Give quality time for your weaknesses and solve similiar problems so that you dont committ same mistakes over and over again. You can give more 3-4 tests as per last 4 year sample papers, analyse the solutions and check if you have better approach to the solution. in the end, revise all basics and formulae.

All The best.

See you have a decent academic records. So that's a plus point for you because every IIM after CAT exam make up a merit list based on your aggregate score which comprises of many factors such as CAT marks, 10th 12th and graduation percentage, work experience, engineer or non engineer, gender with different weightages for different colleges in order to call students for interview and WSAT round. Among this 10th 12th and graduation has an overall weightage around 10-25%.



Seeing the trend from last few years now to get calls from top 3 IIMs i.e. IIM A, B and C you need to score above 99.67 percentile. From other old IIMs like IIM L, K, I and S you need to score atleast above 98.5 percentile in order to get a call. For all the new IIMs by scoring 95+ percentile you can get a call. Even after securing good percentile there is no surity of getting a call from some IIMs like IIM Bangalore which gives way more weightage to work experience and IIM Indore which gives more weightage to academic records even more than CAT marks.



Always aim for a very high percentile in order to increase the probability of converting your call because in the final merit list after second round interview and WSAT marks along with CAT marks have the highest weightage.



All the best for your preparations and exams!!

Target a Min. 95+ to get a call from newer IIM's and a 99+ from old one's.
