Hello student. OUAT- orissa university of agriculture and technology takes admissions by considering both the  scores. That is, rank list is prepared by considering 50 percent of score in boards and remaining 50 percent of score in the exam conducted. So, to always be on safer side, try to secure above 170 mark or at the miimum try to get more than 160. Your boards scores are good, so you would get admission easily if you are above the mark of 170.

All the best
