Frequently Asked Questions
How many free practice questions do I get?
You get a 20-question public practice set for one discipline. It opens in the app demo flow so the experience matches the full product more closely than an embedded page quiz.
Is the free practice timed?
The unified demo is untimed by default so you can inspect the calculator, reference panel, solutions, and review workflow. The full app includes timed exam simulations, pacing analytics, and weak-topic practice.
Does free practice include alternate item types?
Yes. The public sets include multiple-choice and selected CBT-style formats such as fill-in-blank, drag-drop, multi-select, and hotspot where appropriate for the discipline.
How is this different from full access?
Full access adds the full discipline question bank, exam simulations, saved history, weak and slow practice, calculator skills, reference lookup drills, Quick Formula Reference, and analytics for a one-time $30 discipline purchase.
