Tutor LMS has a Q&A feature that your instructors & students can use to ask their desired questions and answer them accordingly.
You don’t need to enable anything to get the benefits of this feature. Your students simply need to go to the single course page front-end section of the course that they are enrolled in. Scroll down to the Q/A section found in the information section.
Here they can easily ask a question and have them replied to.
Once the instructor replies to the question the students will be able to see it there in the Q&A section.
Both the Instructor and student will receive an email notification for any update in the Q&A section if it is enabled from the email settings of LMS.
