Each exam session lasts 120 minutes.There are up to 35 MCQ questions in each exam level (60% theory, 40% practice (hands-on coding)). Beware, theoretical questions are valued at 1 or 2 points each; practical questions are valued at 2 or 3 points each. You need a min. 70% score to pass the exam.

Can I reschedule my session?
Our certification exams are offered in two formats: online with human proctoring and onsite at Testing Centers. Both formats require a human presence, either through a live proctor for online exams or on-site staff for Testing Center deliveries. For this reason, rescheduling policies are in place to ensure availability and proper administration.
For online exams: candidates cannot reschedule or cancel the scheduled test session with less than twenty four (24) hours notice. If a candidate reschedules or cancels his registration with less than 24 hours notice, the candidate may be required to pay an additional fee.
For on-site exams: candidates cannot reschedule or cancel the scheduled test session with less than seventy-two (72) hours notice. If a candidate reschedules or cancels his registration with less than 72 hours notice, the candidate may be required to pay an additional fee.
