My dad made me do Khan Academy because i was 4 parallel universes ahead of everybody and i wasn't doing enough work for online school.
I signed up for GRADE SIX math and the first question they ask me is duh, what's 5+3.
Another thing is you cannot restart quizzes. I accidentally pressed the wrong button and checked because that's what i always do and i had to do the rest of the quiz! Without all these fixes i cannot say Khan Academy is a good learning website for any reason at all.
