Steve Leduc earned his Sc.B. in Theoretical Mathematics from MIT and his M.A. in Mathematics from UCSD, and has been teaching at the university level since the age of 19. After his graduate studies, Steve co-founded Hyperlearning, Inc., an educational services company that provided supplemental courses in undergraduate math and science for students from the University of California, where he lectured seventeen different courses in mathematics and physics. In addition to The Princeton Review's Cracking the GRE Math, he has published three other math books, Differential Equations in 1995, Linear Algebra in 1996, and The Princeton Review's Cracking the Virginia SOL Algebra II in 2001, as well as two physics books, The Princeton Review's Cracking the AP Physics B and C in 1999 and Cracking the SAT II Physics in 2000. Through Hyperlearning, Steve has directed the creation and administration of the most successful preparation course for the medical school entrance exam (the MCAT) in California, where he has taught mathematics and physics to thousands of undergraduates. Hyperlearning merged with The Princeton Review in 1996, and Steve now holds the position of National Director of MCAT Research, Production and Development for The Princeton Review. He currently owns two-to-the-eleventh-power CDs and has seen Monty Python and The Holy Grail, Star Trek II: The Wrath of Khan, and Blade Runner about two-to-the-eleventh-power times. -Paul Kanarek.Leduc, Steven A. is the author of 'Cracking the Gre Math Subject Test', published 2002 under ISBN 9780375762673 and ISBN 0375762671.
