I mean that's one specific example, but I get what he's saying. I'm super verbal and I used to do problem sets in college with a friend that obviously had much better visuospatial abilities than me. >75% of the time he'd be the one that really figured out the question. But then we'd go home to write up our solutions and I'd get consistently full letter grade higher marks on what was essentially the same work.
