If you go to Philippines or Russia, then yes, its good. Many MBBS students go there because fee is very less compared to private colleges in India.

Acharya Prafulla Chandra College is a better option.

For getting MBBS college, you need minimum 540 marks if you belong to general category.
Since you have domicile of Bihar you can get admission in medical colleges but you won't get good MBBS colleges.

In my opinion, Adamas University may be good. But I suggest you that there are certain colleges and universities in Rajasthan viz. Anand International College of Engineering, Manipal, LNMIT, SKIT, etc. These provide placement oriented education and have excellent infrastructure. So in my opinion, you can choose the Anand International College of Engineering, Jaipur and visit the campus for further consideration.
All the best for your bright future.
