This app has been extremely helpful in preparing me for exams. I prefer this model of study to LearnSmart, which serves a similar function with less efficacy. My only complaint is that I cannot go back and view the question once I have clicked "I know it." Sometimes I doubt myself, or I get distracted and forget what the question was, and am forced to guess. Also, there are times I am given extremely similar definitions, with the differences hidden behind ellipses because the definition is so long. There should be an option to expand the answers, one by one if necessary, so that we can see the entire definition and not have to guess.
