I don't understand the point of this existing.
1.) When you fail, you have to get 3 in a row. Not 3 correct, 3 in a row.
2.) Makes you afraid of getting an wrong answer, wrong answer means more Noredink.
3.) Any minor, insignificant mistake will be wrong. And there is no second chance. Let's say you got it right, but forgot a space? According to Noredink, thats wrong and you can't get a second chance.
4.) The Practice is worthless. You have to do the entire thing to pass it. That will most likely take many days to do.
5.) Rage inducing. When you almost are about to get 3 in a row, you fail it, you have to get 3 more in a row.
6.) You will need an cheat sheet to finnish any practice within the due date for it. Or it will take you over 100 answers to do.
