Hi Vasilis,
Welcome to Qsm Pro Support Forum. Hope you are having a wonderful day.
To remove “Correct answer” and “Comments entered” text. Go to Text tab-> %Questions_Answers% text section.
Here you can customize this variable as per your requirements.
The Hint field is designed to be shown only on quizz’s page and not on the results page.
You can add characters to the hints of the answers under advanced settings of the questions. But it is not possible to edit ‘Hint’ text.
Regards,
Kriti
