Includes The BHAT® System
BHAT® (pronounced ‘bat’) stands for “Bubble, Highlight and Annotate Technique“. This is a proprietary system, which is used in connection with our educational services, created by Laureen Jandroep in 1999 that uses bubbling, highlighting and annotation techniques to help students quickly find key answers in their manuals during the open book CPC® exams.
Instead of flipping back and forth between pages where the guidelines are, the answers are right next to the codes when a student takes the board exam. Students have stated the BHAT® system gave them the confidence they needed to pass the exam. Another plus: the BHAT® system also helps coders in their day to day coding work! [Learn More]

Q: What are my payment options, and what’s the difference between them?
We understand that every student’s situation is different, so we now offer two flexible ways to enroll:
- Subscription Plan – Introduced in August 2025, this option gives students a low upfront cost to get started right away. You’ll have access to the course materials, and you can add on Blitz reviews and practice exams later when you’re ready. Think of this as a “rent-to-learn” plan if you’re looking for the most affordable entry point.
- Full Payment Plan – Students who choose to pay in full now receive Lifetime Access to the course and included bonuses. This means you’ll always have the training at your fingertips whenever you’d like to review or refresh—even years down the road.
No matter which plan you choose, you’ll be fully supported with resources, coaching, and access to our learning community. The main decision comes down to this: Would you prefer to keep things flexible with a subscription, or make a one-time investment for lifetime access? Either way, we’re here to make sure you succeed.
We Also Accept Affirm and Klarna Cards.
