First, lets look at the positive side. It teaches you math and English/LA. That's it for that. Other than that, it is the WORST thing my school has ever forced us to do. Once you get in the 80's for your score, you get about 1 point per right answer, and you lose about 8 for a wrong question. I have been working on one skill, ONE, for about an hour, and I am only in the 80's. I hate this so much, it has made me cry, lose all my free time, and more. Also, I made my account JUST TO LEAVE A BAD REVIEW FOR THIS! That is how bad it is!
