Hi. As you know, the cut off for admission into MBBS and BDS colleges this year via NEET is very high. Many students have scored exceptionally well, and a couple of students have also scored 720/720. Congratulations that you have already been allotted a seat. Up gradation with your rank is difficult, but be that as it may, you should still apply for up gradation as you never know when a chance may come up.
