Hey there

In 92 percentile your rank will be around 72k and thus you'll have very less chances of getting any NIT or IIIT. So you should try for other engineering entrance exams like COMEDK, VITEEE, WBJEE, and other reputed exams including jee mains too. as there are good engineering colleges other than NIT or IIITs. check the link if you want to prepare for the exams
