This is not really essential, but it helps to convey the message. We are going to set the check messages to be different colours - green text if the answer is correct and red text for a wrong answer.
Highlight all the cells under the Check heading (you could be really fussy and only Select those cells which have the check function by Selecting the first cell and then Selecting the others whilst holding down the Control or Ctrl key). The details are straightforward - if the Cell Value Is equal to Correct, then Format... the text to colour green, Add>> a second condition that if the Cell Value Is equal to Wrong, then Format... the text to colour red:
Again, confirm that this works by entering answers to the questions (both correct and wrong answers) then save the file.
