JEE Main Scores

It depends on which category he belongs to, if he is an OBC, SC or ST candidate, he will get admission, but if he belongs to general quota then there is a lesser chance of him getting admission.

As far as the admission in DAIICT is concerned, you might not be able to get it due to high cut-off which is AIR 12 K approx.

Hello Mohit,
If only you could have scored just 25 marks more, admission would have been certainty. But, don't worry. I am attaching a link that will predict college for you:

Hi,
You can check your colleges through this link:

Yes, there are some chances that you might get into PEC. There is no surety for it because 53 marks can't confirm your admission to PEC as it is quite a reputed institute, but you hold some chances so go and give it a try.

It will depend on the college or your preferred engineering branch.

Your AIR will give better idea of college than marks. According to this year cutoff, 136 is really good marks and you can get state level college with nice branch. Getting a seat in good NIT's is a bit difficult if you belong to general category.
Cut off of JEE Advance is going to be a bit high because maximum marks were high for general category people.

It depends upon the rank of JEE Mains. 12th mark is just for your eligibility for JEE Mains. Depending upon the rank do check the JOSAA's previous year opening and closing rank to get an idea of which college and which branch you can apply for. About better courses, CSE and IT are presently the best in terms of placements.

And congratulations.
All the best.

It is not possible for you to get NIT as the minimum percentage for SC category candidate for NITs and IITs is 65%.
Though you can try for GFTIs and still fill the choices for NITs too.
