I need to retake exam, for this needs to watch course again, but it's locked. What to do?

Hi gigi, Thanks for reaching out! In order to retake your exam, here's what you need to do: Go to "Courses" from the Menu and navigate to "Completed courses". From there, click on the SQL course and watch at least 30 minutes of video lectures. This requirement aims to help students revise the parts of the course that are most challenging for them before retaking the exam. Hope this helps! Best wishes, The 365 Team
