A surprising number of people, in college, are functional illiterates. They read about as well as I read German back in the day, slowly, haltingly, and with considerable effort. I'm sure a Wonderlic test in German would have given me a low score.
I knew a fellow in college who once suggested we study together, and I said OK. He labored over each question, I couldn't handle it, I wanted to move on. I think he took tests that way also, I think he was smarter than I was, but I got better grades. He could read well, he just wanted to consider every angle to every question. We went to the same grad school and he flunked out after a year.
Have you money in hand and your order in mind.
