I have finished MBBS and am not getting through the PG entrance exam. What should I do?

I have an issue with the fact that a single exam is used to assess one’s ability to become a doctor in India. One not only has to study but also has to battle finances, reservations and discouraging people throughout the study period. It is really unfair that one’s career is stuck at a bottle neck called entrance exam. But then again not many things are fair in this world. I got through this bottleneck but I don’t think I was any better than the rest of the people writing the exam. Maybe I was luckier and maybe I was hungrier than the rest I can never say. You can read my answer to the following question and gauge that I was really a plain Jane of the medical profession.
