Is there is a time limit to do this course

can you please tell me is there is any time limit that we have to do this course after enrolment

No, according to my understanding there is no time limit to complete it, but it will highly depend on your need for the course. also know that the courses you enrolled in, you will have access to them for life.

Although there is no time limit to completing the courses you may want to remember this is after all a subscription service so if you take so long to complete your course(s) that your membership is due to renewal then it might be worth thinking about the pace your learning at and the time your dedication to the learning platform.
