Questions
Does studying still work offline?
The apps run entirely in your browser. The glossary, the drills and the free practice set are on your device from the start and never need a connection. The full question bank loads the first time you open a set — after that it is cached and works offline like everything else. The tutor downloads its model once and then runs on your device too.
What happens to my progress if I cancel?
It stays where it always was — on your device. Cancelling returns you to the free tier; it does not erase your drill history or what you have learned.
Is the tutor sending my questions somewhere?
No. It runs a small language model locally. What you type never leaves your computer, on any plan.
Can I switch which app Pro covers?
Yes. Pro covers one app at a time and you can change which one. If you are studying for more than one exam, Unlimited costs less than two Pro subscriptions.
How do the ebook discounts work?
Buy one companion book and you get 10% off a Pro subscription. Buy three or more and you get 20% off Unlimited. The discount code is sent with your book and applied at checkout. Books are yours to keep either way — the discount is a thank-you, not a trial.
What does the tutor need to run?
A recent browser with WebGPU — current Chrome or Edge on a reasonably modern computer. Older machines, some work laptops, and Firefox cannot run it yet; on those, everything else in Pro works exactly the same, and the rationales on every question carry most of what the tutor explains. If this page shows a note next to the tutor, that is this device telling you it cannot run it.
Is there a student or hardship rate?
If the price is the thing standing between you and sitting the exam, get in touch. The free tier is deliberately built to be enough to study from.
