which college i can expect in jam maths. GEN EWS 1300 rank???plz give name of colleges???
Hello,
If your query is regarding IIT JAM then here is the list of few institutes in which you have chances of getting seat based on your rank and the previous year cut off in round 3 CCMN counselling
- NIT, Durgapur: 1367
- NIT, Jamshedpur: 1634
- NIT, Silchar: 1542
- SLIET: 1679
These are the few institutes in which you may get seat in M.Sc Mathematics under EWS category. Also the cut off mentioned is for EWS category. But in 2021 the cut off is subjected to change depending on number of candidates appeared, difficulty level of examination and number of seats available etc.
To check the previous year cut off for CCMN counselling you can click on the link below

my SC certificate is of 2017 ? is it valid or i habe to get a new one ?? in iit jam admissions .
Hello,
Every caste certificate valid till 3 years in any State and for dental it valid only 1 year. So if you are applying for State admission then it's okay. But if you apply for all India counselling then I'll suggest you that you can renew your caste certificate. Or get new one. It's a better option.
All the best.
if a student do not qualify jam with score lower than cut off does he/she stand any chance to get any nit for msc???
Hey,
The question I believe is framed wrong and that makes it difficult for me to understand and answer accordingly.
As far as I understand from your question No if you have not clear the cut off of your category in the Jam exam you won't get any NIT or IITs for Msc. Even if you have cleared the cut off still it will depend on your rank and marks .
Proper counselling takes place and the one above you if filled the whole seat you won't get one.
Hope you understand.
Thank you.
i get AIR (509) OBC category in iit jam biotechnology. Can i get admission in any iit or Nit or IIsc collage?
Hey,
The seats for Biotechnology in JAM is very less and it seems difficult to secure a seat in any of the IITs at this rank. If you would have secured a rank under 200 then you would have surely got into any of the IITs.
At this rank the college you can get are,
National Institute of Technology, Rourkela
National Institute of technology, Durgapur.
Indian Institute of Engineering and Science technology, Shibpur and many more.
If difficult to get IITs and IISc at this rank.
All the best.
Thank you.
