survey to the course

Dear Experts,

Please guide me through the steps to assign the survey to the course.

My client has requested to attach multiple surveys to the users with a specific timeline.

Eg:

1st survey for after the classroom completion date (it includes the general evaluation that I have already set up via Add evaluation under activities)

2nd survey needs to be active after 30- days of the classroom completion date.

I have created the survey through a question template and questionnaire but don't know how to set up this survey for the course with the specific timeline.
