Hello Bakhtawar, Thank you for reaching out! You can obtain a certificate only if you pass the exam. You have multiple attempts, so even if you have failed the first time, you still have a chance to get the certificate. In order to retake the exam you have to go back to the course and watch at least 30 more minutes of the lessons. Then you will be able to sit the exam again. Good luck! If you have any other questions, please contact us at team@365datascience.com Kind regards, Kamelia
