Am I the only one without a formula sheet?

I’ve gone through the material and haven’t created one flashcard or formula sheet, which is exactly the opposite of how I treated Level 1.

Things just seem to make more sense this level and have practical application to me or something. Just curious if I’m the only person without one.

I haven’t created formula sheet too but I have the Elan one. I’ve never used flashcards. IMO with enough practice a person will remember the formulas no matter he wants or not.
