Questions students ask before buying

Is this the same as the real CompTIA exam?

It is an independent practice simulator designed to train the same style of interactive thinking: drag-and-drop, configuration, troubleshooting, diagrams, and command interpretation.

Can I use this with Professor Messer, Dion, or books?

Yes. Use videos and books for theory, then use PBQSimulator to practice hands-on exam scenarios.

What makes this different from normal practice tests?

Normal practice tests are mostly multiple choice. PBQSimulator focuses on interactive performance-based questions.

Should I offer monthly or lifetime pricing?

Offer both. Monthly works well for students studying now; lifetime works well for users pursuing multiple certifications.
