There is no minimum percentage as such to sit for CAT provided you pass your graduation. Different colleges though set their own criteria for minimum marks. For being in the safe side, try to have at least 50%. I am assuming you are from general category. Hope this helps. All

First of all fill up the form of CAT. Then appear for the exam. Regarding calls from IIM, respective IIM have their different selection procedure and criterias. Kindly go to each IIM and check their procedure. Give your best shot at CAT. All the best!

No, CAT score is valid only for that year. You need to apply and appear for CAT again if you intend to take admission on the basis of CAT score. Hope this helps!

There is a site named testbook.com. You can subscribe over there for the exams you are interested in and you will get regular updates. You can also get study materials and free mocks for all exams.

Hope this helps!

The answer to your question is that it is the minimum eligibilty criteria and not the only eligibility criteria. There are several factors that each IIM considers before selecting/rejecting a candidature.Hope this helps.

Unfortunately you are not eligible for CAT as your marks in graduation is very low and there is no way now that you can improve the same.

All the best for your future!

There cannot be any confirmation as such! There have been cases where even a 100 percentiler has not got call from all IIMs. As a lower limit, above 85% in 12 and above 99+ should do. I have assumed here that you are from general category and  have no work

To be honest, chances are very bleak with the rank you have secured. Keep your other open. However hope for the best and keep your fingers crossed. All the best.

Unfortunately with your academic profile and marks in graduation, you will not get the colleges you desired based on your parameter of best placement. It is better you start preparing for CAT 2018, and also do appear for other management exams like XAT, NMAT, IIFT, TISSNET, MICAT, MH-CET, SNAP, MAT
