IF YOU HAVE TO DO AN ONLINE COURSE WITH ALEKS, RUN. I have to use Aleks for a college math course and let me tell you, DO NOT TAKE AN ONLINE MATH COURSE OR ANY COURSE THAT USES ALEKS. It repeatedly gives you questions that often have no connection to your tests and quizzes, it takes points away if you miss a question, there is NO skip button and the explanations are absolutely terrible. This program has caused me literally meltdowns as I have spent hour after hour cycling through this $#*!ery. It may seem simple at first, but then the next thing you know it['s been 8 hours and you're crying because it deletes your progress if you get one question wrong. This is a terrible program. Save yourself before it is too late
