LOL. Some of the problems were math related and a calculator is much quicker than in your head, like if you add all the numbers from 1 to 16 together, is the final number even? Or something like that. I didn't use a calculator for any, but I did guess on one or two. Anyway, my scores on these vary quite a bit, but are generally in the 120 to 140 range, depending on mood, how many distractions I have, how hungry I am, what the test is like, what types of questions, etc.
