About the work

A closer look.

Tell me the single exam fact you (or your student) blank on when it counts, and roughly when the test is. Within three days you get a small interactive drill built for that fact, plus the one-line rule behind it. It works by making you retrieve the answer cold and telling the difference between three outcomes: you knew it, you guessed right (a smooth wrong), or you actually drew a blank. Guessing right and knowing it are not the same thing, and most study tools can't tell them apart. Useful for exam revision, vocabulary, formulas and definitions. Built from verified sources, not memory. One free revision. If I can't verify the fact against a real source, you pay nothing.
