HESI HELP anything would help

[heartbreakgee]

hi im about to take the hesi a2 exam for the first time on friday and im completely terrified. :redbeathe ive been studying the evolve reach study guide (isbn 978-1-4160-5635-5) and also reading other post about the exam. what scares me is the biology chemistry and a&p part since science is not my fore take. does anybody have any helpful hints or remember anything that they believe that i should review in depth?.....also i have seen a lot of posting about the medical terminology on the test wanted to know if it simple suffixes and prefixes or hospital abbreviations?

i know im asking for a lot but i am not a very good test taker and wanted all the help i can get...:sstrs:
