NIT Surathkal - National Institute of Technology Eligibility

It depends on your branch of engineering.
CS - 2000
Civil - 30000
Mechanical - 40000
Please do share your interested branch of engineering so that I can help you in detail.

In NITs, the admission is based on the merit list or rank of exam NIMCET.
You can write exam after completing BCA / BSc course.
The exam is for 1200 marks and to get admission in NIT Trichy you should score at least 600/1200 and for NITK Surathkal 600/1200.(These marks are for general category).
They vary based on the categories.

You have got good marks, but NIT, Surthkal, Karnataka comes under the top list of NITs.
Not only this, they both are famous for their mechanical branch after NIT, Durgapur and Surat.
So, 139 is not enough as the admission in those NITs starts from 180+ for home quota and 250+ for other state students.
But as you mentioned you are an OBC category student, you have very slim chances to get into it.
I will prefer to give them top priorities in the choice filling.
All the best.

Hi thejas, sorry NITK do not consider CMAT score,they consider GMAT & CAT score.

Hi madhuri , i will suggest you to fill a form and prepare for Gd Pi, because last year cutoff was low student scored 65 percentile in CAT got admission in NITK, this time many students got good score in CAT so work hard in GD PI
all d very best
