WSET level 2 and or 3 for sale??

I'm in Houston and it would be a HUGE help if anyone has a level 2 and/or 3 text book they would be willing to sell me.   I'm going to be taking a 2 day course in July and it would be a dream if I could get a little head start. I found an old level 2 book, but having been published in the early 90's, I'm sure it would leave me at a disadvantage,  especially with new world regions. PLEASE HELP !!
