you need to score at least 36 out of 120 marks, which is the minimum qualifying mark. However, just meeting the qualifying mark doesn't guarantee a free seat. To increase your chances of getting a free seat in a good government polytechnic college, aim for a higher score. Generally, scoring above 90 marks can place you in a favorable position, but the exact cutoff can vary each year based on factors like the number of applicants, seat availability, and reservation policies. It's advisable to aim for the highest score possible to improve your chances of securing a free seat.
