Regurgitation ≠ learning

Regurgitation involves short term memory and micmicking. It does not build new neural connections.

Learning involves longer term memory, synthesis of new perspectives(in the learner), and integration of knowledge across multiple domains. Learning is the building of new neural connections.

I posit that you did not actually learn how to learn and thus just regurgitated your way through math.

I agree that learning is what is important, but I wouldn't assume that GP did not make an effort to learn. Learning an entire field is difficult, and small hints may be all that's needed to draw upon one's learning.
