BDS is also a good stream to choose.My advise will be see whether the college is good or not. and its placement scale.on the other hand droping is also good

FIRST ATTEMPT:-This is to test if you are extraordinary or not. That is why it is also called as "Zero Attempt". Yes it is really tough to crack NEET with Schooling and Boards. Only the extra ordinary can really manage both of these and get a good rank. That is why most of the top rankers are Freshers.

ThiSECOND ATTEMPT :- is the time for the Normal, this is when we stand a chance to get decent rank and grab a medical seat. Most of the medical students belong to this catagory of students. That is why famous coaching centres arrange batches in a way that in 1st drop they are gonna prepare the student for the exam by strengthning the basics and then they are gonna make him/her crack the exam in the 2nd drop year

hope it helps

Good luck!
