I think you have some abstract symbol capability that is not the opposite of imagery.

I lack imagery but also am nonverbal and hit limits in math. I am terrible at rote memorization or application of formulae.

I did well in math up to a point, which may have hurt me. I simply felt answers to quite a bit of algebra and some calculus, but it doesn't scale. I also got accused of cheating a couple times in primary school, when I could not explain my work when arriving at an answer very quickly.
