Your welcome Becca. The truly most valuable purpose of the study group is what you mentioned, getting other's perspectives often helping clear things up you may not have fully understood. Sometimes, I would find myself overthinking when things were so much more simple and vice versa. Engaging your fellow classmates and faculty is most valuable! I wouldn't start worrying about the NCLEX just yet, but when the time comes, there will be a new latest and greatest NCLEX book
out there, just do a little research on them, but usually Kaplan is top notch. Quite honestly I didn't use a book to take my NCLEX, and I had to take it twice passing the 1st time on both (LPN, RN).
Approach your test taking from these angles, what action would not cause the patient harm, ABC's, Mazlow, and learn your normal values and normal function of each body system, this will help you identify when things are abnormal. Most importantly, I had a lot of instructors tell me I will eat, sleep and breathe school, not so, it's important to find some time to unwind, some time to do things you like to do and give your brain a break, it wont be much time, but it is critical to maintain your sanity!!
