Most test prep companies dont press the constant feedback approach (MGMAT for eg has countless rules for verbal SC but does not stress enough on the application part). egmat scholaranium helps to bridge that gap when preparing for verbal. It provides quick feed back of the learned concepts and the ability reached in each topic/section. Ultimately one should target for an ability level of 70%+ in each section to excel in the verbal. This is a great test to complement the egmat verbal live prep course material!
I highly recommend this test for non natives as a litmus test of the learned concepts. In fact you can also take this test coming from other prep materials to check your understanding level of the concepts. Good luck with your prep.
