Dear Arpita,

The eligibility criteria of NMAT completely depends on the institute that you plan to apply to. Hence, you will first need to check the basic eligibility requirement of the university where you want to apply. 

Listed below are few basic requirements to sit for NMAT by GMAC:

• A full-time bachelor's degree with 50 per cent marks in any discipline from a recognised institute 
• Final year students who clear their final year exam in the first attempt with 50 per cent can also apply for the entrance exam
• Applicants with over two years of work experience will be given preference

I would suggest you cross-check with the Institute for any particular eligibility requirement so you can move ahead in the right direction. 

I hope this helps, feel free to write back!

If a student has a correspondence graduation degree, he/she is eligible to apply for NMAT entrance.

You should have minimum 50% in your graduation to be eligible.

Good Luck.
