These are so easy. The first month I tried I qualified for 15 Sit-N-Learn Freerolls, so I got to play 15 of the qualifying freerolls, which later on I found out was a waste of time because you can't get more than one ticket into the next round(I was hoping maybe I could unregister for points or something). Back when I did it there were a lot more people that were registering, they will take 1000 max, but there were about 200-600 in each of the ones I played, so it took a bit longer, but like 65% of them were sitters. In the $ Freeroll, I cashed for $12 I think. I haven't taken any of the quizzes since, even though I can get 100% on each of them...
Good luck on it guys, easy way to make some dough.
