Interior Design Student in Need of Assistance  

Hello, I'm a high school student in an interior design class. My final is a test paired with a presentation, on a poster, a a few rooms of my choice that I have designed from scratch.
My problem is though, I've been searching, reading, and trying so hard to find descriptions of design styles. I'm pretty much looking for a basic description. So if you know of a site that has such descriptions, I'd be very grateful if you would please tell me of it. Thank you for your time!
