"honestly i put off studying for like two months and panicked at the end. found cpbexam.com pretty late and just drilled the practice exams back to back. the mistake review was the part that actually moved the needle for me, seeing exactly where i kept going wrong on reimbursement questions made a real difference."

"was skeptical a prep site would cover the billing regulations side in enough depth but it definately did. the domain breakdown helped me figure out where i was wasting study time. passed first try."
