Nah, you'll have ample time during training (provided you heed the advice here and put in the work!) I sought out and obtained a ton of class materials from people here before I started, and it did more harm than good; I didn't know what was important and what wasn't, so I tried to study everything, and my brain was a bit fried before I even walked in the door--not smart. The training dept will give you everything you need to know, when they want you to know it.
