I am an undergraduate student pursuing Engineering. I need help with how can I prepare for GMAT and CAT and what is the criteria for admissions abroad?

Hi Ronak,
I am a pass out of IIT Kharagpur 2015 batch.
There several institutes which provide coaching for CAT exams, among them I have referred the materials from career launcher and times institute for preparing for Aptitude exams during placements.
 Their materials are right; you may join any of these two institutes.
You may also try for correspondence from the institute mentioned above.

If you’re applying for a graduate-level degree, especially a master’s program, you may be required to submit scores from one or more standardized graduate admissions tests. These are internationally delivered tests which aim to ensure applicants are prepared for the rigors of advanced study, in their own country or abroad.

You can give an exam like GMAT and MAT in the final year of engineering.
Firstly, you start by learning the basics of Mathematics. After that, you have to practice from the lower level to a higher level. Same as reasoning.
An essential part of this exam is English, so you can proceed with basic, practices and read the newspaper daily and also by doing exercises of spoken English.

Hi Ronak, first of all, I would like to congratulate you on the decision of having the clarity to pursue business studies. However, the path is still equivocal. You see, CAT and GMAT are always the different sides of the same coin. It seems relatively easy to view them both from the same lens. But mind you, GMAT is having a completely different set of requirements than CAT. There are many Indian universities which accept GMAT scores like SPjain and ISB. However, CAT is only for IIMs and some other Indian universities. For GMAT, Jamboree classes are good. You can enquire. For CAT, I think you need to pursue your enquiry with TIME. It depends on your location too. Please note that for GMAT getting a score is not the only criteria, you must be having robust SOPs and LORs besides Good GPA at the undergraduate level. Thanks!
