One-Year-MBA in India usually begins in April.
If you are planning your MBA for April next year (say 2020), you should be done with GMAT ideally by April or latest May this year (2019).
Yes. A year in advance.
That means your preparation for GMAT must start 3 to 6 months earlier- that is between October 2018 to January 2019.
And the truth, my friend, is that the actual work begins after the GMAT.
Preparing to get an Admit can take at least 12 to 18 months of work.
Essays, Interviews, Recommendations, Applications and so much more. Plus you have to manage your job.
