With a score of 62 in OUAT and securing 90% in 10th and 61% in 12th, you may have a chance of securing a seat in a government college, but it depends on the cutoff and competition in that year. Government colleges typically have varying cutoffs based on the course and category. It’s advisable to check the previous year’s cutoffs and participate in the OUAT counseling process for more clarity on available seats.
