How the course works
- Cheat sheet. Everything the exam expects you to recall cold, printable.
- Starter test. A few questions per exam domain, with a confidence rating on each.
- Your tutorial. Lessons chosen from what you missed or guessed, each with a checkpoint and a deeper explanation.
- Practice tests and retraining. 50 questions, weighted like the real exam. Every miss is explained and feeds back into your lessons.
- 3 of your last 5 at 80%. That unlocks one full-length test on the real exam's clock: 100 questions in 120 minutes, at its real passing score of 70%. Pass it once and you are ready to book.
Every lesson

On exam day
- 100 multiple-choice questions in 2 hours, closed book, taken from home or an office through live remote proctoring. That is over a minute a question; read every option before you answer.
- You need a laptop or desktop with a movable webcam for check-in, a steady connection, and administrator rights to install the secure browser. A personal computer is strongly recommended over a work one.
- Test in an enclosed, quiet, well-lit room with nobody else present, pets included. The desk must be clear: no paper, pens, phones, or second screens. A four-function calculator is on the screen.
- Stay in view of the camera the whole time. Leaving the room, talking, reading aloud, headphones, or looking away repeatedly draws a warning, then termination.
- Results come back as pass or fail right away and by email within 24 hours. The fee is non-refundable, you must test within six months of purchase, and a retake waits 60 days.
- The credential is valid for five years and cannot be renewed; by then you qualify to sit for the CBET.
