I wanted to take a moment to thank you! I passed the Unlimited Exam yesterday and could not have accomplished that feat without your seminar and booklet of 500 sample questions. As you emphasized in class, practice and persistence worked. Several of the questions we practiced in the seminar where on the test and most were variations with small changes. I just wanted to let you know how much I appreciated your help.
