NIT

If you are a general student, then you will need to work really hard for CSE in NIT ,studying only for 2 hours will not work.

Yes absolutely with JEE MAINS score, you can get into any NITS if you have the necessary cut-off marks.

The chances of getting into those NITS are high but as you have a bonus of SC category. NIT, Surat and NIT, Hamirpur both are good colleges to get into. But if you talk about civil, then you should join NIT Surat. NIT, Surat gives you the best infrastructure and teaching facilities etc. They will provide you with good placement also. You can join NIT Surat. Civil needs better labs and infrastructure to study, so I suggest you to join NIT Surat.

No, you can't because the cut-off for Mains is 75 percent in 12th class. It doesn't matter how many marks in JEE marks you have, you should have 75 percent in 12th.

You need to give JEE advance.

The fees for the same will be high for you than other students.

The simple answer is NO.

The company fills the response sheet and sends it by e-mail/post to the Training and Placement Departments of the respective NITs. Once the details are received, the placement officer and coordinators get in touch with the company and a mutually convenient date is fixed for the Campus Placement process.

As per my knowledge, ICT Mumbai is a great knowledge centre for Chemical Engineering guys. On the other hand, it also depends which NIT your referring. NIT Rourkela, Warangal, Tirchi, Surathkal are also equally good.

Yes you can if you have home state quota for a NIT.
