I got 18/30. Geez!

I never got through the test, my computer kept freezing----that's my story and I'm sticking to it !!!!!

17/30. Though a lot of those were lucky guesses. There were maybe 5 that I knew for sure :) Thanks for sharing!

I got 24, guessed on a few and got lucky, but knew most

I don't think 13 is bad at all!

14: Some (most) of them were lucky guesses!

22/30 guessed on a few, but knew at least half for sure. Thanks for the fun post.

I got 15 which surprised me as I'm not familiar with many blocks. Seem to do the same ones over & over.

21 here too and also a lot of guessing. I only knew about 12 of them the rest were just stabs in the dark.

I got 20 right but I kind of disagree with some of them. And my memory is a little deficient.
