Navigation, Error and Product Version
Navigation in the Final Exam/Info page needs improvements. when we are in information page there is no link option for Return to Exam home page except the link in the header.
After finishing the quiz, at 0 minutes remaining clicking on the answer shows an error but it that's not the user friendly way.
In videos, the product version and size of the data studio and db2 are older version and small size, but when attending the question which depends on version is a problem, also newer versions are large in size. So incorrect information makes downloading problem.
