Physiology Viva Questions for Prof / Stage (1st Year MBBS)

April 23, 2017

Speaking metaphorically, Physiology is a Godzilla — not in terms of difficulty but in terms of size. And if someone, a brave soul decides to study Guyton and Hall’s Physiology, he’ll get his mind numb and would frequently experience study-burnouts without significant learning outcomes. Don’t go the hard way… instead you should choose the smart way. And you can do that by conceptual learning (meaning, the ability to explain something with utter simplicity) which is highly effective and is key to acing your Physiology Viva.

As, Alber Einstein said:

“If you cannot explain it simply, you don’t understand it well.”

And we would highly recommend that you use Guyton’s Physiology as a reference book and NOT as your main book. Because you would never be able to revise it during your exam preparation. It would be great if you use a combination of two books i.e Kaplan and Pocket Guyton. They work best together!

Studying from Guyton would make you feel like Jon Snow at the end… 😀

**Yes, you’re Jon Snow… and you know NOTHING! 😀**

GOOD LUCK! 🙂
