Pretty good. I’d give it a B.
Overall this app was good. I utilized it to supplement my studies and I passed the exam. It was handy and the cost for the extra questions was reasonable.
My criticism comes in that I was unable to submit the questions I had flagged as problematic. Some questions had inconsistent answers, for example there was one about jaundice at 24+ hours in a term baby and the correct answer was supposed to be that it wasn’t an alarming find, but the correct answer per the app was suggesting pathologic jaundice. The explanation that followed described it as would be expected as an expected finding. So the answer and questions were at times inconsistent and I couldn’t flag them. Some of the other questions were oddly worded and I know that’s a tactic used in these tests. But do fix the glitch so the inconsistent questions can be flagged.
