IMPORTANT: Having multiple accounts causes delays in receiving exam results. Creating multiple accounts to avoid a rescheduling fee, circumvent the (ISC)² Retake Policy or to reapply a free exam code is a violation of (ISC)² Exam Policies and may nullify your exam results and/or result in a temporary or permanent ban from (ISC)² exams.
