CAT

Dear!
You can choose any of the course in graduation. There is no such favouritism in Iims given to any specific course. However, for CAT preparation you can join the coaching centers like TIME or Alchemist or Ediwiser. Hope this helps. Good Luck.

Hello,
Nowadays, competition is really tough so cracking any exam is really going to be tough. Both the exams have different requirements, think about your background and which exam is suitable for you because in UPSC exam, you have a deep knowledge of one subject with at least good knowledge of all the subjects.

Yes, you can give one more attempt if your goal is top notch institutes. Gap years is to be considered because when it comes to placements we have to justify the gap.

Hi Valmik,
Surely, you can get a good institute with a good CAT score, the selection process of every institute considers your academic but it is given very less weightage.

You need to have 50% or above for admission in Christ.
