Ive tried most of the leading test prep apps, this one being the most expensive by a wide margin. The questions are pretty much the same, but the look and feel of this app leaves a lot to be desired. It looks like something from the 90s, full of weird sound effects and puffy clouds that add nothing to the actual learning. You can save yourself a lot of money with one of the other alternatives, most of which are easier to use (and easier on the eyes).
