Nice one wizzy.

Donpre:
Thought this thread was gonna be updated daily?

BTW, where dem bosses at? Come devour this questions

Drguzzykola:
Wow! Nice one whizzy. still in pre-medical class, am so much naive to those Q , can't just wait to burst into preclinical and knock questions like this,, but anyhow-anyhow , nothing spoil , will take this as an opportunity to learn from senior one before then. Medic per Excell

Thewhizzkid1:

Yes o. But I'm surprised nobody has shown up till now to attempt the first questions.
