Good Morning, I am preparing to take the Hesi A2 at Chamberlain in a couple of weeks. I am very excited and very nervous for the Biology and Chemistry part of the exam. Any tips on what basics to focus on? I have been on allnurses for quiet sometime, but have never made a post or asked any questions. So, forgive me if this is not the correct way. Does anyone have any experience with Chamberlain? Thanks in advance! -Alexis
