Help!! Taking on-line political science

[RNbethy]

So I'm taking a political science course on-line, and I have the entire course to complete in about 1/20th the time that most people do it in!!! Yahoo!

I just submitted a proposal today and realize there are some things I missed... (like a major objection to my thesis!!) It would have helped to finish all my readings from the textbook before starting the proposal, but I thought I had read all the pertinent stuff...(realized I was wrong today.. a few hours after submitting it!)

QUESTION: Do I email the instructor so he knows I'm aware of the mistake? Or will this look unprofessional? I just want to get this off my chest... but don't want to appear foolish in the process
