FAQ

What's included in Free vs Pro ($14.99)?

All free practice with no signup; all 880 verified questions with a free account. Free accounts also get 10 AI Tutor questions per month. Pro ($14.99 one time, lifetime) adds 1,000 AI Tutor questions per month, the weak spot drill mode, the full progress dashboard with radar chart, timed exam simulation, and every future feature we ship. There are no subscriptions, renewals, or hidden charges.

How long should I study before the real exam?

Most HVAC technicians study 2 to 4 weeks before the real exam. Beginners should plan for the full 4 weeks, about 20 to 40 hours; experienced techs already familiar with refrigerant systems may only need a week. The readiness signal: scoring 85%+ consistently across 3+ practice sessions. The real passing threshold is 18 of 25.

Is the Pro $14.99 payment really one time?

Yes, the Pro $14.99 payment is really one time: one payment, lifetime access. No subscription, no renewals, no auto-charges. You get every Pro feature we currently ship plus every future feature we add. The price increases when we release significant new features, so locking in now at $14.99 is the best long term value.

Do I need to create an account?

You don’t need an account to start practicing: select any section and begin immediately; scores save in your browser. A free account unlocks the full 880-question bank and saves your progress. Pro adds the AI Tutor at full capacity, drills, and advanced analytics.
