Heres the Summary of your simple checklist to stay compliant for a 3rd exam payment
(1) Finish your first PMP® exam within 30 days after your original training
(2) Finish all quiz practice before the first exam.
(3) If you need to take the second exam, purchase a quiz extension / resubscription, and finish all quiz practice before your second exam
(4) We must be able to pay for your third exam within your 12 months of exam approval. You track your exam approval time, because we don't. (Track your eligibility dates and exam free through your PMI login dashboard.)
