Hi, MostafaHemdan! If you are looking for Official Microsoft Courses (what the Training Partner program officially uses), Courseware Marketplace no longer fills that role.
Here's some links for reference for you.

If you are an MCT and you are planning to teach a class, you should be getting your materials through MCT Lounge with the Learning Download Center. Your Training Service Partner company should be familiar with how to do this. For your students, they will access Microsoft Learn as their textbook.
If you still have questions, feel free to ask!
