Great app
I have been using this app to study for my ptcb test. I pay the ridiculous monthly fee to access my missed ones to keep practicing but the worst part is the fact I have caught so many errors on an app I pay for, I’ve reported them multiple times. And they are never fixed. I’m pretty disappointed. It’s helped to study but not worth the money
A good way to see what you already know and what might need some attention. Some questions didn’t have enough information to figure out correct answer and some had duplicate answers and others had only three answers showing and the fourth one blank.
Overall it is pretty helpful but at times two multiple choice answers would be considered correct. Ex: takes 1-2 day or 24-48 hours, both are the same thing. Or find the mode and there are equal amount of 4 and 8 showing. Frustrating and I don’t know if what they’re teaching is actually correct.
Greatest for studying
I’ve really enjoyed using this app to practice for my upcoming exam. I love that it’s free as well. Great quality and the developer really proves they care.
