It's difficult to get a seat with this marks. I'll talk about Maharashtra, the scenario here is that by scoring 177 , any private college will admit you either in BDS or MBBS.

But as per my survey, average fees for BDS is 4 lakhs per year including hostel and mess and for MBBS it is 10–12 lakhs. If you have that much of amount to shell , then you can opt for private colleges.

But 177 isn't the score that will reflect your potential and caliber, don't get me wrong. Every one is at par, if you work hard you will achieve heights.

I am assuming this was your first try, don't get disheartened, take a break for 1.30 months, chill, roam discover yourself, ask yourself the amount of patience you have to get that doctorate degree in your hand. And then finally when all's good, start from the scrap. If you are getting 200+ in NEET,17 one year of sheer hardwork would surely get you to more marks that you deserve. 

The decision is obviously yours. All the best.
