NIT

Then u will be judged on ur jee mains score.

No chances if u r GEN or OBC

You won't get any NIT with this score. So try getting in private. The best you can target with this score are: Sastra university, UPES Dehradun, UTM Shillong, VIT, Galgotias etc.

U have a chance for some NIT's not the top one's but u have a chance.
n I hope u attempted the jee advanced exam.

Hi Jatin,
Kindly refer the JEE college predictor mentioned below:

Kindly filter out the branch / college / location as desired from the above link.
I hope this information helps. Please feel free to revert.
Wish you luck.

No, Try for State level govt colleges.

Well as per past data, you can get a seat for sure if you are from State Board. In case of CBSE/ICSE that's not a sure thing or if you'll get one then it will be NIT's of lower ranks.
Also the branch and college you will get depends on how efficient you're while filling choice.
If you didn't do it correctly then chances of getting a good college with good stream will reduce to a great extent.
Hope it helps.
All the best.

With your given information I think that you might get Mechanical Engineering in NITs like NIT Raipur, NIT Jalandhar, NIT Kurukshetra which are good NITs.
