Final quiz question answer

The answer to the question on the magician being able to read your mind is incorrect
The \sqrt{.25} is 0.5 unlike in the screenshot

On another note
I have completed the course, however, in some sections I haven’t completed the optional quizzes. So why am I not able to view my certificate?

Hi @sundeep,

  1. Thanks for pointing, will correct it asap.
  2. Can you please make sure if you’ve completed all the feedback forms?
