Hand recallit your PDFs and links, or just describe it, and it builds you a tutor that shows exactly what it could verify against your sources. Practice by drilling or talking it through, and it grades you straight: the points you got, the ones you missed, and the line it checked.

The method
The same three every time. You only ever do one at a time — recallit holds the schedule so you don't have to keep it in your head.
01 · Describe · in plain words
Drop in PDFs and links, several at once, or name a topic in your head. Pick how it should teach: straight recall, rules you have to apply, or real what-do-you-do situations. recallit builds the cards and cites the exact line each one came from. What it can't verify, it holds back and shows you, instead of inventing.
02 · Practice · your way
Run a quick drill when you're busy, or just talk it through when you want to explain things in your own words. You pick, and you can switch any day — the grade behind it doesn't change.
03 · Remember · at the right time
Answer well and it drifts away for weeks; struggle and it comes back sooner. When you sit down, what's waiting is the stuff you're about to forget, not what you've already nailed.
The honest math
Any subject
Hand it whatever you're trying to keep in your head — for yourself, or for someone you're teaching. The way you practice can change; the honest grade behind it doesn't.
"Talk through the ideas, and the shaky ones keep coming back until they stick."

"Drill the dates on the train, then debate the causes on the weekend."
A topic · “teach me World War 2”
"Rehearse explaining it until you actually can, with the paper's own lines as the check."
