Pathophysiology Question....

I am starting an ABSN program in May with Path being one of my first classes. I am reviewing A&P since it has been over 20 years since I first graduated from college but am wondering to what depth I should be brushing up? I am surprised at how much is coming right back to me but I don't want to obsess over too much of the minutia if it is really not critical. Any advice would be extremely appreciated!! Thank you!
