BDS in India

Hi Rahul,
The priority order can be as follows:
1. MBBS from India (from a good medical college)
2. MBBS from Philippines (from a good medical college)
3. BDS from India
First of all you can give priority to MBBS course as there is a need of good medical professionals in India and abroad.
Secondly, it's important to choose a good college whether in India or Abroad as the Indian government is very soon planning to implement an exit exam for doctors in India before they start practice and go for PG in India. The objective is to improve the quality of education in Indian colleges as except for a few colleges our medical education system needs drastic improvement.
Doing MBBS in Philippines can have an added advantage as you can prepare yourself for USMLE and try to gain residency in USA. But choose good universities.
Hope this helps. To get admission assistance for MBBS abroad you can check my profile.
