Prophecy Pharmacology Test

Hey guys,
I have to go in to take the Prophecy RN Pharmacology test... I am terrified... Anybody had to take it for employment and can give any advice or insight as to what I need to prepare for? Anything would be appreciated.
The version that I took several years ago was basic, very basic dosage calculation, IV flow rate based on drop factor and common sense nursing considerations. It took about ten minutes. This was three years ago.
