CAT Scores

It depends from one IIM to other. You must have above 96 %ile in CAT to get admission in top IIMs. It also depends upon your category if you are in reserved category.

There is only one XLRI and the same is in Jamshedpur I wonder from where you got XLRI Chennai and Bangalore.

But they have already closed the applications for MBA.

To get a call from an old IIM, your focus should be on getting above 95% marks in CAT with sectional cut of around 80 percentile.
If you belong to reserved category, you can receive 80 percentile, then you can perform well at GDPI also.

You have to score above 60 percentile in CAT.

For example- Candidate-1 with 99 percentile.
This candidate with CAT 2016 percentile score of 99 has sectional percentile scores of 100 in Quant; 98 in DILR and 80 in VARC
After FMS awards weightage: 30% of 100=30 in Quant; 30% of 98=29.4 in DILR; 40% of 80=32 in VARC. Total points the candidate has scored in shortlisting process are 91.6
Now Candidate-2 with 97 percentile
This candidate with CAT 2016 percentile score of 97 has sectional percentile scores of 94 in Quant; 92 in DILR and 99 in VARC
FMS awards weightage: 30% of 94=28.2 in Quant; 30% of 92=27.6 in DILR; 40% of 99=39.6 in VARC. Total points the candidate has scored are 95.4

CAT score is valid for only one year period. For example if your appear for CAT 2017 which will be held this year in Nov-Dec 2017, you can use CAT score for seeking admission MBA or PGDM in academic session of year 2018-20 in IIMs and other B-Schools.

Dear Aakash Karki,
FMS, Delhi CAT cut-off would be for FS quota around 95 percentile. For general admission, it would be around 98.65 percentile. All the best. Try to get a good score as it will help you out.

Generally, the cut-off stays for DFS around 95 percentile for general category. However, you might need to score more to account for your relatively less marks in math as their is a separate weightage for them.
