JEE Main

Sorry dear,
There is no chance for you to take admission in a government college through JEE Mains.

Yes, you can get direct admission in SKIT, Jaipur.
If you fill the form of REAP exam then you can take admission in SKIT through the counselling process.
Otherwise, you have to apply for the direct admission.

If the given ranks are your category rank. Then, I will have to say that it is enough to get you into DTU. DTU is one of the topmost college of the country and holds a good reservation for delhiites.
If you are resident of Delhi then you can go try for it, you might get some non-core branch there. Or maybe, you will have to go for another options.

What is your JEE Mains score?

No, sorry. It is extremely difficult and nearly impossible if you are a general category student.

It depends. If you are from Odisha then yes and if not then it might be difficult.

Participate in the counselling process. Your marks are above the par line for SC students (32).

Hello Prahalad,
No, you should not spend 2 years for IIT after class 12th. Many students spend only a maximum of 1 year and that too only if they have the confidence of getting into IIT by doing hard work. Also, you need to answer the question, why did you spend a year after class 12th? When the companies come for placements, they always look for the continuity in studies.
So, choose wisely. If you can get admission in IIT then drop 1 year, if you cant then don't waste time as many have failed in JEE Advanced even after spending a year.

You should have mentioned your rank and category.
If you belong to general or OBC category then there is no chance of any govt. college.
You can get any good private college through CSAB special round counselling.

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.
