Hey there, 

As per your query I would like to tell you that according to your rank and based upon the previous year cuttoff marks you need to chosen the option of BDS first. 

Because the cuttoff marks for getting admission in government medical for MBBS course are increasingly. It is hard to find to get admission in government medical college for MBBS. 

Hopefully it's will be useful to you. 

GOOD LUCK.
