Reflection notes for LOR

AArsalan

I have asked a former professor for a letter of recommendation and he accepted to write it. I want to send him a package including all the relevant materials for the application. I do not have my personal statement yet, but I thought of writing a reflection notes on what I learned from his class, and how that is going to help me in law school. I couldn't find more information on this, but is this a good idea? Will the notes help the professor in any way while writing the LOR?
