HELP! Bombed the HESI Entrance Test

I took the HESI pre-entrance test today and BOMBED scoring 72.5%. I need a minimum of 77% to even be considered for the program.

I got the Elsevier review book and studied for 10 days. I took the 4 practice tests in the back of the book but I dont think it helped enough. There were questions on the practice tests that were not covered in the review chapters.

I got a 68% on the Math (improper fractions killed me) and had trouble with the Bio section. I did OK on the AP part but there were questions I didnt know even though I studied the review book. I completed AP I this
Fall (got a B+) and I am registered for AP II starting in two weeks. I passed Algebra I and II with a B+.

I am frustrated. I am a 3.6 GPA in the pre-nursing classes, I work a full-time job and a part-time job as a Nurse Assistant in the ER (16 hours a week) to make me more competitive when I apply. I go to school two nights as week to complete the pre-reqs. I am a returning student after 20 years and I truly want to be a nurse. The clinical experience in the ER I love and I have learned a great deal in a short period of time

Does anyone have any advice on how to better prepare for the re-take test? I have two weeks to get ready and this re-take is my last shot for me to apply for the Fall 2009 class. You can only take the test twice in one
application year.

Thanks for your help and guidance
