CAT

Hello Akhila,
Various Management Institutes or B-Schools have different dates for applying into their respective programs. Institutions such as Goa Institute of Management release their notification before CAT exam. But, if you want to apply for IIMs, or IITs, they release their respective cut offs for their programs after declaration of CAT results.

Hello Krishna,
I would not recommend you to pursue MBA in any foreign countries without entrance exams, as it will lower down the standards of the colleges. GMAT and GRE are relatively easy as compared to national level competitions like CAT or GATE. So, I would suggest you to appear for entrance examinations and try your luck.

You stand a decent chance of getting into DMS, but a cumulative score of your GDPI/Written exam is also taken into consideration.

Every college have different cutoffs, so according to that it is mentioned.

You can definitely prepare for CAT and if you prepare well you might even get 99+percentile. But, even then getting into an IIM will be quite difficult, because they give a significant weightage to your past academics as well. But, there are also some very good institutes at par with the Iims, who do not give that much weightage to your past academics, provided you have a good profile and a very good percentile in CAT.

Hi, ISB, Hyderabad accepts GMAT and GRE score. https://www.shiksha.com/business-management-studies/course/post-graduate-program-in-management-indian-school-of-business-gachibowli-hyderabad-112040.

Sorry, but CAT exams are for Masters in Business Administration. So, before you do it you should have to complete Bacholer's degree or any equivalent course. After Diploma, you can't apply for CAT.

No. CAT is one way to get in MBA colleges. You can give MAT XAT GMAT ATMA CMAT IIFT NMAT etc. Many options are there. Don't limit your options only to CAT.

Go for online class options. You can see whenever you want and can study from wherever you want. With an ease. And can clear doubt from n no of videos and you can do it for free or paid also. See as much as YouTube video of different professors for your CAT preparations. All the luck to you.

Your graduation score is a bit less, I would thus recommend you to try for a very high percentile - in the high 90's to stand a chance.
