CogniPrep vs iPREP
iPREP mostly prepares US candidates for trade, certification and aptitude exams, from the IBEW electrical aptitude test to Raven’s Matrices. CogniPrep is built around employers’ assessment providers and game-based tests. They overlap on two tests, the TSA CBT and TestGorilla, which this page compares directly.
