If you answer a question correct, you get only a few points like 6 or something. But if you make a MISTAKE, you lose a lot of points. And the more mistakes you make, the more points you lose. I also don't like that after the first question answered, you can't go look at explanation a few times again. That means you have to search on Google if you can't remember the explanation. the explantion. the explenation. explenation explenation
