Hi Priyanshi,
JEE Marks and Cutoff changes every year. Therefore, we cannot say accurately to how much score to fetch a Good NIT's/IIIT's/CFTI's. But we can predict the approximately from the previous year's data. To be on safer side, a score of 160-170 or above is better. Also, it depends on home state and Other States JEE Rank.
Hope it helps.

Yes, lateral entry is available. You can go for lateral entry test conducted by the institute.

No IITs can be opted through JEE Mains exam. You have to first clear JEE Mains and JEE Advanced exam.

Hello, As per your mentioned question, there are no IITs which give admission just by opting JEE Mains exams, but for NIT, you have to clear JEE Mains. You have to clear both JEE Mains as well as JEE Advanced. Also, you have to score well in JEE Mains to get a good NIT.

I wouldn't suggest you to drop 1 year, because you will need to study extra hard to beat JEE Mains. But, if you really want to prepare, Kotak is best option for you.

No, 70% marks score is too low to be considered for admission in any good private college. I would suggest you to study well and try again next year.
