You'll have to sign up, but it's VERY easy. Right now, I have it set on "Randon"......which is just a mixed bag of questions. But I can set it for 100's of different topics!
The questions will change daily and you'll be scored daily. Number of correct answers and time go into your score.
I just set this up, so I may not yet have all the answers to any questions you may have, but let's give it a try and see how we like it!
Ive got it saved just above the GFTC group on my favorites, I stop in for a few secs and play, then onto GFTC. That works for me to be able to remember.
