How Second Shot works for Microsoft Certification Packs?

For Microsoft Certification Packs: With each exam pack, you get one free retake for each exam you do not pass the first time. If you do not pass an exam in a Microsoft Certification Exam Pack, you must request a retake voucher at the Prometric website.

For single exams with Second Shot: If you fail your exam the first time you take it you may use the same voucher for your retake exam.

Note Prometric will provide a retake voucher through email within 72 hours. Each voucher pertains to a particular retake exam and cannot be used for other exams.
