In case you did not get the minimum score on the theoretical online exam, you can retake this exam after 1 month. If you fail the certification, you can retake it after 3 months of the last attempt failed. You can continue studying to achieve the skills needed, review the recommended free self-paced courses again and attend the instructor-led courses that give you hands-on experience and in-depth expertise. The establish times had been defined taking into account that if you fail the exam on the first attempt, we consider important to have some practice in projects before taking the examen again. Note if you fail the theoretical online exam, or the whole certification, you must pay again for retaking it.
