Dear Doctors, 

Many students purchase the app and don't complete the course. Only the students who complete the video and attempts the tests are the ones who ace the exam. We want to ensure that you just don't subscribe to the app and also complete the videos , take the tests and finally ace the exam. 

Here is the challenge for you.  Out of more than 50 hours of video uploaded, how many hours you have watched and comment it. 

Thank you  Surgery Sixer and Elixir Apps Team
