Do i get admission in bits pilani if i score 85 percentile in CAT?

You can get a call above or around 80 percentile

Yes with a decent profile if you score 85 percentile in CAT exam then you can get a call from BITS Pilani. Eligibility criteria is that you need to be an engineer with scoring above 60% in graduation.

With 85 percentile you can even apply for some other good colleges like IMT Ghaziabad, TAPMI, MISB Bocconi etc. which are much better than BITS Pilani for pursuing your MBA degree in any specialization course.

If possibly you can push your percentile to 90+ percentile then you will be able to open a whole new series of colleges available to get admission for you like IIT Kanpur, Kharagpur, Delhi, Madras.

As very less time is left for CAT exam so in order to push your percentile you need to brush up on your basics and give up lots of online mock test and analyse each test's solution thoroughly which will help you in overcoming your mistakes and come up with a strategy to attempt your paper which will definitely help you in improving your marks and percentile.

All the best for your preparations and exams!!
