The test for me was okay...As far as all the subjects, Science is definitely not my forte' so I studied my off on the science section of the study guide and ended up doing well enough. I felt the Kaplan Nursing Entrance Exam book helped me a lot more than the actual ATI guide! Oh also, purchasing the practice test on the ATI website helped as well.
I took 8 pre-req classes over at NU but the tuition was getting to be too much for me!
BTW, City College actually waived Health Essentials course because I took A&P and English at NU (in case you have taken these classes already =) I still finished up Health Care Essentials last month for Grossmont which is the easiest class you'll ever take!
