Hi. I always suggest doing a proper internship provided the hospital allows you to be directly involved in the treatment of patients.
There are various reasons:
This is the time when you get to apply your knowledge practically and can make as many mistakes as possible but you'll be supervised and corrected.
You get the hang of how a hospital works and how to handle patients and their relatives
There are several things you get to do while doing internship that you might never get to do in future coz you'll go into one particular speciality. eg. Conducting labors, assisting surgeries, etc.
Internship is one year you can award yourself after 5 years of studies and before another 3–6 years of direct/subtle inhuman atrocities.
It doesn't matter if it takes one extra year to crack your PG entrance. There is more to life than just an MD. And you deserve that one year of your twenties that you'll never get back. Friends in other fields have absolutely amazing twenties. You can have one tenth of that atleast.
Practical experiences themselves do help a lot in entrance examinations. Remember it's what you do that you remember much better than what you have read.
Hope that helped! Cheers!
