Such a horrible percentage brother but stil if you're from general category then cutoff for jac board or any other state board is top 20 percentile of that board and you can expect something around 63-64 percentage marks will be the cutoff. I got admission in a NIT in 2018 and that year the cutoff was something around 318 which is 63.6 percent so if your luck is good you can expect that you wil be eligible for all NITs.

If you are from general category As a basic condition, candidates appearing/ have passed class 12 with minimum 75% marks can appear for JEE Main 2019.

For SC/ST/PWD candidates-  65% marks in aggregate.

So you are not eligible for counselling in any govt. colleges

You shall go for private colleges.
