Good evening,

I'm afraid that I have to put the reality here. According to JEE Advanced guidelines, the apllicant must have secured atleast 75% in class 12th board examinations to apply for JOSAA Counselling, i.e., to get into IITs, NITs etcetera. I would suggest you to either apply for board examinations improvement exam next year and prepare simultaneously for JEE or you can always go for other engineering colleges. Good luck.
