Christopher Dyer, MBA, first became interested in the mechanisms of adaptive testing after taking the GMAT for the first time. By studying the test itself, he was able to re-test and dramatically improve his initial score. Using what he learned from his own test preparation, Christopher has been helping USM students prepare for the GMAT, the CAT, and the GRE since 2003. In addition to teaching standardized test preparation classes, Christopher works in customer service research at L.L.Bean. Christopher is a native of Maine and has earned a BA and MBA from the University of Maine.
