I need to take the HESI A2 test in 2 days and am having trouble finding some important information, specifically, do they provide a periodic table and do you have to memorize unit conversion factors or are they provided? I can't believe that expect you to memorize the periodoc table (my chemistry professor doesn't know most of it!), and what is the point in memorizing how many cups thre are in a liter? The Elsevier study guide provides no help on this. thanks!
