Test on a Wordpress site?

Question

Web development

There is a site - hack.helpugroup.ru
I made a test through the wp-pro-quiz plugin
Everything would be fine, but if the answer is wrong, the correct answer is shown on the left.

I tried to dig into the plugin source to hide the output of the answers. Everything is in vain. The very essence of the question is to remove this derivation of the answers. For those who really help, I can slightly reward. Thank you for your attention.

Answer 1

In the WPProQuiz admin -> next to the desired test, click "edit" -> Questions-Settings -> Hide messages "Correct" and "Incorrect"

Answer 2

Yes, I already did that. The message just disappears, and the response is shown as before.
