If you watched the videos attentively (which we hope), it should not be a problem to pass the exam.
The questions cover only topics that were discussed in our videos. Most of them are multiple-choice questions. Some are to be answered with true or false. There is a time limit of 20 minutes, and you have to answer 20 questions.
Once you have submitted the exam, and passed at least 80 % percent of it, you can download the certificate in your account dashboard.
