Instructors don't have to "send" a test to a Medical Director for review. They already have access to view all tests within their school, even if the test is a draft or is disabled.
If you would like a Medical Director to review your test, you may just want to send them a message in the system asking them to take a look at your test.
Once they review the test you can see their review by following the steps outlined in this article here.
