I would seriously like a refund. This app is filled with glitches and problems from misspellings, poor grammar, and many of the questions say “incorrect” when the correct answer is chosen. Literally not a single answer shows up as correct, yet after clicking “show explanation” it’ll just say that my original choice is the correct one.. also, in the “show explanation” tab after a question, it will describe a few of the choices as having the same definition... if you are going to charge for an app, make sure it’s isn’t filled with errors.. this is a poorly made app.
