NIT

You should score at least 130-150 to get enrolled to an NIT.

No, you should not take a drop of 2 years to appear for JEE Main for admission in NIT or IIT. For seeking admission in IIT, you have only two chances.

You can go for BITS Pilani. The fee is high but it thas the best placements.

Nothing is required to float from slide, documents are only required when you freeze the allotted seat and also when at the time of admission you need all the documents mentioned in the JoSAA information bulletin.

I think NIT- Allahabad is better with ECE. There, you will get a good atmosphere of coding and ECE is one of the top branch of NIT-Allahabad. NIT-Allahabad is better in all manners.

Hi! Thanks for the A2A.
The thing is that NITs and IITs, or for that matter, even IIITs do not have lateral entry. While this may be counted as a certain disadvantage to a section of students, do try to understand that the rigorous preparation which churns out effective candidates cannot be replicated in any way in a lateral system. As a result, no, you can't get into an IIT/ NIT.
Hope this helps. Best of luck for your future.
