Learndash

Hello, I have a website with learndash. I have 50 tests, one per subject, the student can only take one test at a time. It would be possible to put some function where the student can choose between several tests. For example, a page where there are 50 tests, and the student chooses 3, 7, 45 and does a mix test.

The image is my web, the indivudual test.
What price?
