I am a student that has been using this website for years. I genuinely like using technology in class, but this is the one site that me, and LITERALLY EVERYONE ELSE is my class HATES IT! The diagnostics are excruciatingly long (Took me an 120 minutes to finish) and every time I get a question incorrect they rub it in my FACE and talk to me like a baby when they know I'm in 6th grade. For some reason, in like 50 of the lessons, they teach me something that ends up being incorrect when I check it in the calculator. Just now, (I am writing this at the same time as doing a lesson) the computer said 4x4 is 15! THEY'RE TEACHING KIDS INCORRECT THINGS! Plus, if you don't do the computer lesson, for some reason It'll be marked MISSING! It is literally an UNCHANGABLE GRADE! I think I'll have notify my principal about the 1,000 OTHER KIDS THAT AGREE WITH ME! I hope I never see this site again.
