I just barely made it through mathematics in high school just because of my more-or-less intuitive grasp of geometry and spatial puzzles. Ofcourse then I had to do real
algebra in university which was quite difficult.
I don't think my brain is very visual, but I do have trouble remembering people's names - I have to *remember* to remember their names, or I'll forget it in 5 minutes.
On the other hand, I love idioms and weird information, and I have no trouble at all remembering those - my brain is full of trivia and out-dated expressions.
