Dear Naveen,

Once you to the home page of your course (by clicking on the course title), all the chapters / modules are displayed to the right of the screen. Below the title of each module (whether completed or not completed) you will have topics covered in that module in blue colour. Click on the topic you want to go through again. It will take you again to watch video and review quiz link. That's how completed module videos can be viewed again.

Hope this helps..

MADAM IS IT POSSIBLE TO DOWNLOAD THE VIDEOS AND SEE OFFLINE. BECAUSE MOST OFF THE TIME I WILL BE WORKING IN REMOTE PLACES (VILLAGES)WHERE THE INTERNET FACILITY IS NIL AND IT MAY HELP FOR ME TO TEACH THE SAME TO NEEDY PEOPLE AND EDUCATE
