JEE Main Scores

Yes, if you have cleared the cutoff score for SC category students, which is given below your score card.

Chances are there if you have home state quota in the states having lower NITs. Otherwise, it will be very difficult for you to get into NITs.
PS: Assuming that you are a general category student.

There are many good engineering colleges in Indore, Bhopal and Jabalpur. You can look for any of the engineering college in Indore, Bhopal or Jabalpur.

It will be difficult for you to get into Nirma University with this score.

Sorry dear, but 21 marks are not enough to grab you any govt. college.
You should try for any private college which offers admissions through direct means instead of JEE Mains rank and score.
All the best.

If you are qualified, you can apply for NIT counselling through www.josaa.nic.in.
The same counselling is valid for all NITs, IIITs and also GFTIs.
To get the colleges other than NIT, IIIT, and GFTI, select the colleges where JEE Mains scores are accepted and just fill up your JEE roll no. and marks in the application form so that you can get admission.
All the best.

Since this exam is conducted only once a year, there are no chances to write this year again, but you can appear for the JEE mains exam the next year. Maybe if you take the exam next year with full focus then you can get IIT.
All the best.

You can only get private engineering colleges based on this rank of yours.

Hello Krisnakant,
These days, marks scored in 12th do not count. However your score in JEE Mains is of vital importance. I suggest, take a break of one year, study with full determination and dream of entering IIT. If you have aim, I am sure you will do well. Presently unfortunately there is no chance.
