I have taken Veritas Prep with Cliff Smith twice. First time was back in 2003 where I scored a 710 after taking his class. Second time was in 2013 when I scored a 740 after taking his class. He is incredibly patient and focused on the key topics and strategies to take you to that next level. His Cliff's Notes are incredibly helpful on topics you haven't learned in 10+ years. Most of all, he is very supportive and responsive to questions and concerns when things aren't going well. I ended up having to take the GMAT twice this time around because I did not get the score I wanted on the first attempt. He helped me diagnose what might have happened to me on the actual exam and I went back, retook it a month later and got the score I wanted. Thank you Cliff!
