Cutoff marks for BVSc in OUAT change every year depending on the number of applicants, difficulty level of the entrance exam, and seat availability.

OUAT considers a combination of your entrance exam score, 10th standard marks, and 12th standard PCB average (each contributing 25%) to determine your final rank.

Entrance Exam (25%) = 68 / 100 * 25 = 17

10th Standard (25%) = 92 / 100 * 25 = 23

12th Standard PCB (25%) - You haven't mentioned your PCB average. Assuming an average of 84%, then PCB weightage =  84 / 100 * 25 = 21

Estimated Total Weightage: 17 (Entrance) + 23 (10th) + 21 (PCB) = 61

It's recommended to search for previous years' BVSc cutoffs at OUAT. This might give you a general idea of the required weightage for securing a seat. You can search online using keywords like "OUAT BVSc previous year cutoff" or check the university website.

If you belong to a reserved category, the cutoff for your category might be lower, increasing your chances.

Even if BVSc seems unlikely, with your good scores in 10th and 12th, you might have a chance in other allied agricultural science courses at OUAT that typically have lower cutoffs compared to BVSc.
