Meet Tooki
Tooki is there in every lesson. Your tutor can see the question you just got wrong and which answer you picked, so you can work through the confusing part together.
Hi, I’m Tooki! Stuck? Let’s work it out together.

It falls fasterIt overshoots and climbsNothing changesYou are picturing a bigger step as faster progress. That holds until the step is wider than the dip it is trying to land in.
Drag it up and watch what happens.
Past the middle it stops settling and starts bouncing.
So what is too large a step actually costing you here?
It asks before it tells
Tooki starts with a question to see where you are. Say you're stuck and it walks you through the idea.
It knows what you missed
Which lessons you passed, which you scraped through, and the exact wrong option you chose on the question that's about to matter again.
It gets you to try it yourself
If the screen has something you can work — a figure, a circuit, a robot to program — Tooki asks you to try it and say what changed. Then it explains what you saw.
