Hi ghg07,
Any of the recent versions of the Official Guides (going back to 2013) would be fine to use during your studies, but it's likely that you'll need to invest in a variety of additional resources as well.
Since it sounds like you're just beginning your studies, then it would be a good idea to take a FULL-LENGTH practice CAT Test; you can download 2 for free from www.mba.com
