This is possible using Advanced Actions and variables. After every question, On Success you can set a variable to 1 and create a custom screen where you can show/hide the tick mark graphic based on the variable value set.
- For question 1, on success, set x=1
- On the results screen, correct tick mark graphic is hidden. If x=1, then show the correct tick mark.
Like this you can do for all the questions. Will wait for others also to comment for any quicker solution.
