There is a small chance that the cutoff might reduce in round 3 in Punjab for the SC category under the defense quota. The change depends on how many seats are left after round 2 and how many students with similar marks are still in the race.

If some seats remain empty or if a few candidates withdraw their admissions, the cutoff can drop a little. This sometimes happens in special quotas like SC or defense. But if the seats are already full or many students with similar scores are still waiting, the cutoff might stay the same.

Since your score is 367 and you are close to the round 2 cutoff, you have a fair chance if there is even a small drop in round 3. Still, it is not guaranteed because the drop is usually very small in the final rounds.
