Dear Mahesh, you need not pay the fees for the gap year. If you paid 2nd year fees while you were studying 2nd year and 3rd year fees before joining 3rd year, you are good to go. You pay the tution fees only once for a year no matter you fail or pass. You will have to pay the exam fees everytime you appear for the exams but not the tution fees. Tution fees once a year is good.
