Ok so after months of thinking about this ive decided that I want to go back to school to become a LPN. I was very excited I finally found something I really would love to do, then I heard about the NET. At first I thought no problem I'll buy a book and study it, I got Kaplan book to be specific. I started studing and found that it is VERY hard, now I am second guessing if I can do this or not, in this book everything seems so hard, even the reading which i thought I'd have no problem doing, there are words I have never even heard of in my life. So my question is, how hard is the net REALLY?? I know this is a very silly way to put it, but how much harder is it then getting your GED, I've never really taken any big tests besides that one, and if I have no chance at the NET I mine as well not waste my time. Thank you for any help.
