Hi, 

Tough choice. 

But if you are really passionate about becoming a doctor and thia time you get a good college, then personally I will suggest you to drop that course. 

Many times some aspirants join other courses and they keep preparing for NEET along with that course. When they get a good college, they leave that course. 

So wait for the results now. And post result declaration take this decision. Talk to your parents before taking any step. 

Good luck! 

Yes u can drop if u got a mbbs seat or any other course seat in which you are intrested drop your seat wity full confirmation that u will a seat and interest in mbbs. 

All the best.
