Before exam day, run at least two timed mock sessions with the SurePassExams desktop or online test engine; practicing against a real clock turns the official time limit into a comfortable rhythm instead of a source of panic.

To file a claim, submit a scan of your exam enrollment slip together with the official score report (PDF) within 2 days of taking the exam, and your claim will be processed within 7 days. The candidate name must match the payer name, and the policy does not apply to exams taken within 3 days of purchase, to purchases where the exam was never actually taken, or to free materials and expired orders. Prefer an alternative? Instead of a refund, you can exchange your purchase for two free exam products of equal value while keeping the update service on your original product.
