The quiz questions never change order-they are never randomized! Yes there are 700 questions but that means to get to the new material you have to go through the same questions, in the same order, as when you started.
Imagine being a serious technician trying to study right before the test and having to skip through the same hundreds of questions hundreds of times before you get a new question every time.
And also, the rationale of the questions are junk, they don’t go through explanation.
This is a low effort app-don’t waste 20 bucks on it.
