Hello @FionaPattis081
Test videos are optional. They are an excellent resource to receive feedback for your audio and video qualities. You do not have to wait for a reply from the Udemy review team to start producing your course. You can see in this link how to add sections, lectures and videos to your course:
https://support.udemy.com/hc/en-us/articles/229605768-How-to-Add-Sections-Lectures-and-Video-Content-to-Your-Course
Do not hesitate to write in a ticket if you encounter any uploading issues in your course through instructorsupport@udemy.com
Best of luck and happy new year!
