I honestly felt the HESI and NCLEX were a guessing game. I did not study for HESI and somehow managed to score 902. I took a Kaplan course for NCLEX and did some practice questions everyday for 2 weeks before the exam and passed in 75 questions. I felt it was a lot better knowing how to answer the questions, rather than the material. My friend studied everyday for a month (over 7 hours a day) and knew all of the material, but took 265 questions in order to pass. The questions on NCLEX vary so much, you never really know what you're going to get. I felt like I failed, but to my surprise I didn't! Good luck!
