I went from taking the exam twice, getting 4's to this time finishing with an hour to spare, answering 28 confidently, and having plenty of time to work on the harder problems and check over my results. Dave's shortcuts and techniques helped tremendously, and was what I needed to pass.

David became interested in probability in high school while attending the 1988 (and 1989) Hampshire College Summer Studies in Mathematics. He graduated from Harvard University in 1996, majoring in mathematics, received his Ph.D. from Cornell in 2002, also in mathematics, and spent three years as a postdoc at the University of California, Berkeley, in the department of statistics. He was a TA for a number of classes, including probability, at both Harvard and Cornell, and was the instructor for both Probability and Stochastic Processes while at Berkeley. His student evaluations for Stochastic Processes were tied for the highest of any instructor in undergraduate classes in the Berkeley Department of Statistics in the Spring 2004 semester.
David has only recently entered the actuarial profession, and completed the preliminary exams from November 2005 to November 2006. He currently teaches full-time for The Infinite Actuary.
