ALEKS is probably the worst experience I've ever encountered it my entire adult life. The program seems like a good idea in theory, but in reality causes me countless loss of hours and sanity. It's a simple math software that requires you to get 2 or 3 questions correct in a row to pass a lesson. This doesn't seem like much, but once you consider the factor that missing a question, causes you to miss the current question, AND the question you previously answered CORRECTLY, it's very easy to get annoyed. To me, this makes no sense at all, who's brilliant idea was it to say, "Hey, how about if somebody get's a question wrong, lets not only take away the point for that question, lets take away the point from the previous question too!" Anybody who doesn't have the patience of God himself will fall victim to this site's evil trap. The only use for this is for lazy teachers and college professors that don't make their own work.
