Stole a lot of test questions

I downloaded several apps to study for my CEN, this one seems to have stolen most of its question bank from the PocketPrep app. The “original” content seems to have grammatical errors or asks strange questions like “what kind of inhalant is nail polish remover” with an answer of…. “Nail polish remover.”

Developer Response ,

Dear docrock184in,
First of all, thanks for your feedback. We have a team of over 30 content writers who create practice questions. The content is then manually and automatically checked for quality and originality before being uploaded to the app.
It will be very helpful if you can report incorrect questions to our support team using the link to our website on the app's page. We will discuss the reported questions with our content writers.

Not a fan

Too many repeat questions! Not a very large question bank and there are grammatical errors!
