DO NOT BUY Ok, damn, I really wish I had googled this company before I gave him my credit card. Sure he sent the test cd's but as soon as I say that it was windows vista compatible, and the copyright was [protected], I knew I was probably out my 215 dollars. The call seems so genuine, and the "oh I forgot to mention the 15 dollars for shipping" should have sent up the red flag. There is no www.testprepservices.org so pretty much all of the phone scammers promises are garbage. I disputed the charge on my credit card in hopes that I'm not out the 215, I'll be glad to send these garbage CD's back to them, I'm afraid to put one near my PC. DO NOT BUY
