As a person who just passed the NCLEX I will tell you how I personally got through nursing school. For classes like anatomy and chemistry things that hard core memorization was required to pass, I would read the chapter, take notes at home, then leave space in those notes for my notes in class, but really focus on listening to the lecture in class for understanding rather than note taking. But once I got into actual nursing classes, I honestly did this. I would go to the resources provided online for the book, print out the outline of the chapter, review the outline briefly and then go to the book for things I didn't fully understand from the outline. Other than that I went to class with a good night's sleep, used an app on my computer which allowed me to take notes and record the lecture at the same time. Then when I got home I would take a bath or shower to relax and listen to the lecture again, saying the information out loud and listening to UNDERSTAND. I did this, and didnt stress at all through nursing school, I never studied anymore than 3 or 4 hours and never straight through because I listened to what my body was telling me. Stress can make it hard to focus, affecting you grades, so while everyone in my class was getting on meds to deal with the anxiety, I was skating by with high Bs and some As. I'm not saying this will work for everyone, and I did study hardcore for finals and midterms (12 hours 100+ page study guides). But the rest of the time I learned to understand, not memorize and I feel I did better in clinicals and on the NCLEX because of this approach. Best of luck to you, and I hope you get through this and feel less stressed soon!
