Sean Selinger developed GMAT Pacer technology in 1994 while a student at Cornell University. GMAT Pacer technology allows an individual to train for perfect timing on test day. The pacer watch paces the user using a time display. 800score later used Sean Selinger's invention for over 100,000 students preparing for the GMAT and GRE.
Numerous companies have tried to copy the pacer design, but none have successfully integrated it into the test as the Test Pacer does using 800score's copyrighted design. Sean Selinger's test pacer has proven an invaluable tool for test preparation. The Test Pacer is available for download at 800score.com.
