Hello,Shivani singh!!! You have not mentioned your jee mains rank in this question.

But according my knowledge this year approximately 80 percentile is qualifying for general category.

So,you may not get NITs and IITs.these are most reputed colleges in india that gives seats on mains rank.

But, now a days many other good engineering colleges are also giving seats based on jee main rank. You can apply for them to get seat based on your jee main result.

Hello Shivani. First of all, congratulations on a stellar class 12 score. Even though you JEE score is slightly on the lower side, you stand a great chance for admissions into good colleges. The key reason being your high class 12 score, which can reduce the negative impact of your JEE score when the merit list is prepared. 

So keep the fingers crossed. 

All the best.
