Medicine & Health Sciences

I will suggest you to complete your Masters in Medicine i.e MD, give MCAT (Medical College Admission Test) for USA and Canada. Afterward completing the same you can apply for Post-Doctoral Fellowship or Internship in the same.
You need to get a registered licesure to become a Doctor in countries such as Canada and USA.
However, for graduate studies and Post Doctoral Fellowships in Canada you can check out universities such as:
1. University of Western Ontario
2. Dalhousie University
3. University of British Columbia
4. University of Toronto
I hope this helps. Do write in case of further queries.
Now, for MCAT exam:
MCAT eligibility criteria - Although there is no specific
