Congratulations for getting accepted into nursing school. That's a huge accomplishment! I've attended a LVN program which is equivalent to your first year of nursing school and what I would recommend to prepare for nursing school is you want to study like you are making the transition from student nurse to working RN from day one. That means taking what you learned in A&P and problem solve like a nurse. The gaps I encountered was taking what you already know and applying it to nursing subjects. For example you've learned about blood pressure in A&P. When you get to nursing school you are going to learn about taking a patient's blood pressure. Then you will learn that there are classifications for blood pressure like normal blood pressure, prehypertension, stage 1 hypertension, stage 2 hypertension. Also, when you were in A&P and you learned about blood pressure, you also learned about blood pressure from the different ages (infant, child, adolescent, adult , elderly) That can be a challenge at first, but it's not impossible to learn. Just be a person who is always willing to learn.
Other resources ask your professor for help. Youtube RegisteredNurseRN is a great resource and Mark Klimek audios as well as Saunders book
