The entire idea behind "grading" doesn't work.

I simply space on a Fibonacci sequence, and the fact that it is overkill for being able to answer is a feature. Because my goal is to react the right way in similar situations, not to get an answer right on the written test.

One could grade how close or accurate one's reaction was to "reacting the right way in similar situations", which was the stated goal:

> "Because my goal is to react the right way in similar situations, [...]."

I seek that kind of grade in separate prompts telling me to review for that issue.

Those reviews are generally conversations with my wife.

I'm happy to say that I've been passing with flying colors. (Mixed with some regrets that I didn't start this many years ago...)
