PN admission testing for college

Hi,

I am scheduled to write the pre-admission test for the PN program at Humber College, Toronto, in May 22. I have been out of school for MANY years. Can anyone give me a heads-up as to what to expect on the exam? What should I be studying? I'm more worried about the Biology and Chemistry sections than the Math and English.

If anyone has taken this exam in the past few years, some insight would be greatly appreciated!!!
