Let's just say, I could either do IXL or Study Island. I choose IXL. This website does get annoying, but it's better than most other places. So, just try it out and if you don't like it, too bad. But yes it is unfair bc if I'm at 79 and I get 1 wrong, it takes me back to 60, then I get a question right, and it brings me up to 63. It's unfair but better than Study Island.
