Hi, The plugin is very good, but is there any possibilit…

“evaluating the answers later”? No.

“and not showing how many marks they have got on submission”? Yes!

If you don’t want to show a user what questions were right/wrong an you want to hide their score, then make sure that “Highlight correct / incorrect selected answers on completion” is disabled. You can then add the following CSS to your theme’s style.css file to hide the score.

.hdq_result {display: none !important}
