I used this app at then end of my preparation about a week before my exam for test endurance. Several questions were wrong, contradicted themselves (the rational explain that “A” was the answer but it was marked as wrong), or were missing the scenario when the question was “based on the scenario” Also many questions were the same question so you don’t really get as many questions as they claim to have. Out of all the tools I used (NBCOT study pack, TherapyED, TrueLearn) this one was the least helpful. Some of their content comes from TrueLearn. The questions are too easy to actually help prepare you for the exam. If you’re using it to gain knowledge it might help, however if you want to prepare for the test this app is not worth the money.
