Hesi A2 Entrance exam for chamberlain college of nursing - illinois 2011

Hello everyone, this is my first time using this website! I am getting ready to take my Hesi A2 entrance exam in august. I am kind of Freaking out! I have taken biology, chemistry, and one semester of A&P. I did purchase the study guide for hesi and another nursing entrance exam book. My question is, has anyone taken this test recently? If so, was is REALLY hard? I have studied all of the information from the vocab words and on, just finishing up A&P. How difficult is the science and what should I really focus on?! I know the basics of the lipids, proteins, carbs, ect. And miosis and mitosis, the cell. I don't know a great deal about the krebs cycle and electron transport chain, just that it happens in the mitochondria... Should I be okay with bio or should i go more in depth?! Thank you to all of you and god bless.
Well I don't attend your school I took my hesi in febuary and past do yourself a huge favor and ask your advisor for nursing at your school if you have to study chem bio and anatomy or do you concentrate in the English and math and vocabulary. My school just focuses on English and math so i did not study the other subjects it is hard if haven't been in school for 10 years like me so I had to really study the math and memorize the vocabulary which was easy take the test in the back of the book every other day to see how many u missed the less the better study fractions and ratios a lot
