hi,

see as per the nits fees payment structure policies students have to pay the semester wise fees before the commencement of classes of semester. since you have enrolled on 2020, you would have two semester completed upto the counselling of jee main exams. due to covid 19 the schedules were changed in the past, but for 2021 it would be same as earlier years. so you have to pay the two semester fees, now coming to the  leave from college I suggest you to wait for jee mains result and counselling process. if you get your desirable college in counselling, then you may go for the admission cell of nit kkr and take necessary steps to cancellation of current candidature.

Hi Aspirant,

Yes you need to tell the college officials about leaving the college  and they will provide you with the official leave.And as per jee mains exams you can give it once in a year and as much time you want.Then you give the JEE advanced to get into any good iits.You will have no problem but you need to unenroll your name from accounts counter and ask them officially to provide you a leaving letter.

Hope it helps!!
