In what order should I learn this so it stops falling apart?
Tell Vectra where you want to get to. It orders what has to come first. Without an account it can only order the concepts you type in yourself — and it says so.
Or run it on your own lecture
With an account, the order comes from your lecture's recorded dependencies and what you've already demonstrated.

Want Vectra to actually teach you through this?
The free tools find the problem. Vectra is the teaching engine behind them: it takes you through what to learn, checks what you actually understand, and changes how it explains when something doesn't land.
