I started working on my master thesis a few weeks ago. When I talk to my supervisor and try to discuss new ideas she always starts to explain very basic material that is only tangentially related. Sometimes even repeating what she said in our last meeting.
This leads me to believe my supervisor assumes I do not know what I am talking about when presenting my ideas. And even worse not knowing some very fundamental stuff even after she explained it to me.
I know it is hard to judge what other people know, but this makes it very hard to discuss my thesis with her.
How can I politely let my supervisor know of the level of my knowledge to have more interesting discussions about my work?
