  8. Should be able to retake learning modules and retake exams.

    Should be able to retake modules and retake exams. I work on this from office and need to disconnect unexpectedly at time due to work.
    I noticed that if I have to leave during a final exam then the exam automatically submits even if you have not finished the exam.. and I cannot retake..

  13. Course Completion Certificate linked to Linkedin profile

    Course Completion Certificate linked to Linkedin profile
    It would be better to post/link the Course Completion Certificate and/or Badges to the Linkedin profile. I think it would also advertise the Cognitive Class at the same time giving the user more credentials in the data science Field

    I atttend the final exam, but haven't got any score.

    I selected the answers for all the questions, but nothing happened when I click "check", so I clicked to submit the test. It told me the score will be displayed on the progress page. But the score is still 0 on the progeress page.

  18. update the link in DS0105EN>Mod 1> Creating an account page

    In DS0105EN>Mod 1> Creating an account, it asks us to go to datascientistworkbench.com and create an account. But if you try to do it, it redirects to the Cognitive class page. I spend a while going in circles-frustrated that I was following the steps in the video and yet not getting to the virtual Lab page...It was only when I got to the lab page that I saw that the link is now https://labs.cognitiveclass.ai/....

  19. Add a course completion indicator in course overview

    Currently, it seems impossible to check progress or completion for a course from the completion page. This is tedious, especially for people with distributed time slots and lots of open courses.
