College Answer

Most candidates exhibited a structural approach with reasonable understanding of 
the pharmacology of atropine although there was a lack of precision (anticholinergic 
is correct, competitive muscarinic antagonist is more precise). Some answers did not

needed to be accompanied with detail if marks were to be awarded.
