I can learn quickly if in a state of fascination or obsession. I can also cram rather well, but there isn't much retention from cramming.
Generally, I will be slower than others until a sufficient amount of repetition. I'm like this with math, for instance.
Let's say you gave me tests examining how fast I can solve arithmetic and/or algebra problems. I'll be slow at first. I might even struggle with efficiently calculating what might seem to be basic arithmetic computations. However, if I continue to run through these tests, I will eventually start solving them with lightning efficiency as I internalize the patterns and processes.
