All of the questions are there, but the correct answers aren’t always the ones that the app indicates are correct which means the “show explanation” section on each question is essential. Except that the explanation isn’t always for the question that was asked. Between those two problems around 1/4 of the time you’ll be wrong, whether you’re actually right or not. It’s harder to keep track of your statistics when the app thinks you’re wrong. But at the very least it has questions and answers, so you can still learn from it even it won’t help you to figure out how well you’ll do on the test.
