so I am having my college exams and will not be able to devote time to course to complete it on time. I will definitely complete it after my exams. will i get my certificate or will there be any issues for me ?
It won’t be a problem. The course will prompt you to update your session date, but that is just so they can keep sending you reminders.
Yes, it won’t be a problem as Tom mentioned, as long as you have a valid subscription or aid for a course. You can reset course deadline as described here.
