I don't think that most people can do that. In fact, I think only the ones that already understand a topic can realistically give an estimate of the percentage of their understanding. Someone who "got" 25% or 45% of some material will usually not see their progress.

Fair enough! If you don't understand the material it makes sense you wouldn't be able to properly judge how well you're doing.

Thanks for the thoughtful response
