Take2 Re-sit Exam Option

Arrange your re-sit exam
If you have purchased Take² and an unsuccessful outcome occurs for your initial exam, then the re-sit option it is enabled. When your official exam results become available, you are notified by e-mail to schedule your re-sit exam. It will be conducted through online proctoring offering you flexibility to take it from your home or office, at the time of your convenience. You have up to 6 months to prepare and take your re-sit exam from the date of your initial exam.

While buying the initial exam simply make sure to add the Take² re-sit option

In case you forgot to purchase Take², you have nothing to worry about! Just remember to add it for the exam of your choice through your PeopleCert Candidate Profile, up to 15 minutes before sitting the exam.

Take² is an add-on service that becomes available only when the initial exam linked to it has a “fail” result. Take² is not transferable, non-refundable, and cannot be redeemed for cash or credit, even if it isn’t eventually used. Candidates must schedule and take the re-sit exam within 6 months from the date of their initial exam. Take² is exam-specific; it cannot be used for any other offering and is valid only for the exam originally purchased. Failing to show up for a Take² exam appointment or not rescheduling the appointment prior to their scheduled appointment forfeits candidates’ ability to use the Take² generated voucher. It can only be purchased up to 15 minutes before sitting an examination. Take2 is not available for purchase after a failed exam.
