Hi Bhavani, the cutoff varies every year based on various factors like number of test takers number of seats available difficulty level of exams and category of the candidate etc. However going by the past cutoffs, I am sorry but there are very less to no chances to get VLSI course in IIT Madras. This course is the most sought out and hence cutoff nearly above 800+.
