Live coaching

I want to take full advantage of the 20min coaching calls weekly ( this is my 3rd week in scholars ) but I have yet to setup a call because I am not sure what to talk about. I feel like the material I listen to and read all sounds logical if I follow it completely and the only thing I sometimes struggle with like everyone are my thoughts but it is up to me to work toward changing them.. my question in this case would be, could I have any benefit to a coaching call ? If I feel like I understand the materials and just need to keep working toward applying it as best I can?
