GDPI

The CAT cutoff above 70 is very good enough for getting a call for GD&PI. BITS Pilani conducts its admission process for MBA programmes through CAT and GMAT scores only. BITS Pilani MBA 2020 cutoff will be made available by the institute after shortlisting students on the basis of their CAT and GMAT scores. The institute shortlists all the candidates who have successfully applied for the MBA before the last date. Admission of the candidates into BITS Pilani MBA programmes will be purely done on the merit basis. The following the parameters considered in selection of a candidate.
1. CAT/XAT/GMAT percentile
2. Educational background
3. Work-experience (duration and profile)
4. Extra-curricular achievements
5. Awards or scholarship received
6. Interpersonal skills
7. Statement of Purpose
So keeping your educational background and sports achievements in consideration, you deserve for getting a call.

You have a fair academic record. you should follow the counseling process, but nothing exactly could be said. You should check last year's cutoffs to get an idea about your chances.You will have pretty decent academics if you manage to get 8.5 in graduation.
Assuming, you are gen male engineering. And, by any IIM means old IIMs.
You need to score above 99.5%ile for IIMA. For others keep decreasing 0.5%ile as per the ranking of IIMs.
In case you are not engineering, then the cutoff will be lower. And by God grace, if you are not gen category, cut off will be further low. Remember gender factor is also there. Suppose if you not male then.
Moreover, if you are fine with new and baby IIMs also, then target for 90%.
