Generally I liked the course and I find it useful and convenient to have the information organized in topics. I was already familiar with large part of the material, partially because of tinkering with the watches by myself in a try and error manner. But it is better to have all the essentials arranged together by a professional like Mark.
Suggestions: for getting started with watch repairs and restoration hobby, one also needs to have some hints like where is it better to get the watches from, why their value is so different, what types of movement are better from the spare parts point of view, etc.
