Hey Nidhi.

The marks u have obtained is above the cut off marks this year in ur respective category. But if u are wiling to do further studies from the IITS and NITS  then u might not get the seats there as ur marks are not enough to get that.

see u r from the core branch and one of the most crowded branch in gate competition. So ur marks must be above 40 to get goood IITS for pursuing ur further studies.

hope this will help u. Ask me freely if u are having any query.

good Luck
