CAT

Generally, it depends on the fact that how strong are your basics I.e till 10th. Mathematics and all.
If that's fine and you believe you are strong in basics.
You can have some time for you.
Else, it is suggested that you may join in the first year itself.
mostly students tend to join it by the end of 2nd year or 3rd year starting.
Anyway. there no set rule for this.
But it is good that you join it.
The earlier the better.

Hello Shubham,
Not at all, you need not worry about it. During the campus selection, companies give more importance to your interview process, overall performance (academic + Extra-curricular) during your two years' MBA program and your MBA entrance exam(s) and past academic scores (10th, 12th & B Com), rather than seeing which was your graduation degree.

Hi,
This answer is confined to IRMA admissions. In IRMA admissions process, there is no weightage for academics. The weightage for CAT score is 40% and 10% weightage for IRMA's Issues of Social Concern test. Rest 50% weightage is for GD and Personal Interview. The admission into IRMA depends on all these. Academics doesn't affect the admission procedure.

Not only CAT or CMAT you can also attempt other examination like MAT XAT etc as it is compulsory for admission in the college and every college has their own policy for selecting the candidate through the entrance exam.and your national sports certificates will be a attraction but not a concession.

Mostly, CAT exam is held in the last week of November or in the 1st week of December. It's not fixed, but CAT exam is held first and other exams are held after CAT till the month of March.

Cracking CAT and all other competitive exam is not that difficult but not that easy first prepare plan for what you want to do and how you will achieve it then start with the tasks related to the plan define priorities so preparation for CAT requires already 9 months if basic concepts are claw then 6 months including solving practice papers so do not worry, concentrate on what you have and then kick start for the new task.
