VNIT Nagpur - Visvesvaraya National Institute of Technology

You will not get a seat in NIT Nagpur in CSE with 69 percentile. You may get a seat in some IIITs in some least branches( not a sure thing).
But if you are Home State student of particular NITs or IITs you may get a seat .
You will surely not get any seat in Josaa rounds . So you need to opt for CSAB special rounds so that you may get seat in some NITs or IIITs or GFTIs for some branches . CSE is not a sure thing but sometimes you will get due to luck. It depends on the number of persons who have more rank than you appearing in CSAB rounds and number of seats left in those colleges in those particular branches .
As you mentioned 195050 category rank the chances are really low , you may not get a seat . So try giving JEE again and prepare well this time .

Join in some engineering college and prepare for you sems and next JEE and give your best ,work hard.
Join in some engineering college and work for you sems .
