I highly recommend Richard as a tutor.
In school he was one of the big-dogs who just always got consistent marks.
If you want someone who will actually sit down with you and explain everything to the point where you know it like the back of your hand, then Richard is the man for you.
Gopi is definitely a genius. If understanding every single biochemistry equation (stochiometery included), or deriving all the pharmacology and physiology equations from scratch isn't enough evidence, I don't know what is.
Get in quick before spots run out!
