How to document my chess lessons?

Hello,

I'm taking online chess lessons since last December and now the lessons get more complex, more discussion of positions and their options and what happens if....

Does anyone have an idea how I could document these lessons for myself to go through them again afterwards? I often can't remember anymore what we were talking about certain positions, because I'm not able to listen and follow the board and think about the problems there and write it down at the same time ... 

You all have a nice Sunday and I'm curious which solutions you found or ideas you have! Thanks!

you record it on skype to video. i do it with my students all the time. when your conversation is done you get a message presenting you with a downloadable to the video for 30 days.
