We take at least one HESI each semester. We had pharm last semester, and our instructor gave us a "topical outline" that we could fill with things to study. She did the same this semester, but they're pretty general. What I just bought and haven't really used yet is the HESI NCLEX review book - just look it up on amazon
. It's green and maroon. It doesn't have a separate pharm section, but it has practice HESIs for everything from Fundamentals on. All the items are weighted by difficulty on the HESI, so your percentage score isn't a factor of how many you got right. The most important thing, from what they told us, is don't kill the patient. When you answer every question, make sure that there is no way that whatever you choose could kill the patient, and you should pass. Our is worth 20% of our grade in pharm and fundamentals, and it jumps to 40% for Med Surg. I thought the questions were extremely hard for Pharm, but even though I missed about 7 (and guessed right on several others) I scored a 99% - over 1000 actual score, but HESI provides a percentage score as well for instructors who are using it for part of your grade. If you miss easy questions or kill a pt your grade drops a lot, if you miss something they deem difficult it doesn't hurt you much.
