Welcome

Welcome to your Big Mock Exam. 

Thank you for trusting PTB to support your journey to certification.  Your PTB Big Mock Exam combines a computer-based test (CBT) that simulates an authentic test experience, with 185 peer reviewed questions, and corresponding reviews featuring detailed explanations, breakdowns, and rationales.

Your access is open for 6 months from the date of purchase. You will have two attempts to complete the mock exam within the same six-month period. This is deliberately restricted to discourage answer memorization that creates the illusion of improvement.  

PTB recommends you wait several weeks or months, depending on when you sit for the exam, to make your second attempt. The longer you wait, the more likely you are to forget the content, and as a result, the more valid the measure of your knowledge.
