Hi Cynthia Nondumiso ,
The course https://www.openlearning.com/courses/cpraedfirstaid/ explains on their course landing page the below: 

Quick facts about the course:

• This course does not offer a certificate. However, do not let that stop you from learning one of the most useful skills you could have in any environment: work, home, or outdoors. To know more about a certified CPR course, click here.
• The course is self-paced. That means you can take your time to go through the course content and the activities.
• The course activities are NOT to test you. They are there to get you thinking and applying your newfound knowledge, and also, to get you participating in the course's online community.
  
  For course-specific and content-related queries, they would need to be answered by the course facilitator. You could either comment within the course for the facilitator to reply, or you could send them a direct message on their profile page, if they have chat enabled.
  If you have any platform or technical issues, you can always ask us via support@openlearning.com
  
  I hope the above helps. 
  
  Kind regards,
  Shannen
