I understand your eagerness, and I appreciate that because I was the same way, but let me give you a warning statement. When first semester starts, it will be an onslaught of information, dates, schedules, and times. You will feel overwhelmed, overloaded, and stressed. When the semester begins, you will learn everything you need to know. Get your books ahead of time, but don't start reading. Without some explanation and context, none of the information will mean anything to you.
I'm about to start third semester (2 semesters, and 11 months left until graduation) and I am burnt out on nursing school
. I love nursing, and I am passionate about the work I will be doing as an RN, but I am tired of school. I'm sick of studying, reading, writing papers, taking tests, stressing, and feeling totally overwhelmed and clueless. I make As, and I study enough to maintain good grades, but I don't study more than necessary. I am a good student, but I am tired of nursing school.
Take your time, pace yourself, and don't jump into it all at once. You will burn out on nursing school as it is, but if you start making nursing school your whole life before you even start, you will burn out even more rapidly. My advice for what to do beforehand is this: rest (you will be chronically sleep-deprived during nursing school), de-stress (you will be stressed all the time), get your supplies, including books (get them, don't start reading unless you were instructed to do so by your professors), and enjoy your freedom while it lasts.
Also, congratulations and good luck!
