Here is the Math test to try. I am afraid you might get lost in other math tests which are posted.
I asked my children to try the test-they scored 80%, 79% and 80%.
Good idea, I’ll get mine to do that. Will be interesting to see if dot program helped, though I only did the numbers. 
That’s a neat test. Really interesting how the extremely brief showing forces you to use your “right brain”.
I was amazed that I was getting all of them right when I first started taking it, at how perceptive I could be. I ended up getting 100% after 20 tries and then I quit. Thanks for sharing!
