I don't think scoring this marks (501) , you need to take a drop. Because this is your HARDWORK and dedication itself which has brought you a decent enough score. GMC Bhopal looks difficult at this marks to be honest, but you can go for GMC Vidisha or GMC Ratlam.. GMC Bhopal is expected to have cutoff of 543 this year and u seem away than it.. GMC Vidisha and GMC Ratlam will have cutoff in the range of 480-500... Doing MBBS from a government college is the first priority and choosing a particular college should be second. I guess you don't need to take a drop and should opt for this colleges.
