I did one once and was told that I did rather good, but wasn't told the score and did not ask either.
But I do not like them - not as a tool to measure intelligence.
One simple reason is that time tends to be a factor. I am usually finding a solution to every problem, but I also tend to need my time. Now the problem that I have with time being a factor in such tests, is that being faster/slower is more often than not pure luck. If you go a wrong route first, you will take more time. And since humans are not computers, retry time is a factor. Example: If the solution can be only be found by going from left to right and one (by pure coincidence!) starts by going from top to bottom, you'll get a worse score. That's what I call bullshit.
I suck at mental arithmetic, but I can train this before such a test and become really much faster. But I cannot train/improve my luck in regard to going the correct route, the designer of the puzzle had in mind when creating the puzzle, first.
But even if time wasn't a factor, I'm not sure how useful these tests really are.
