Formula 1

I work with this gorgeous girl and she randomly invited me out to watch the Monaco Grand Prix at a bar this weekend. She said that she's a huge fan and I let her know that I don't know much, but I'm excited to learn about her passions. I'm nervous about making a good impression, so if anyone can give me any beginner insight as to how it all works, I would be very grateful. Is there a "season"? Are there points that the teams score from race-to-race? Who are the big teams? Is there any current drama going into this race I should know about? Thank you all for your help :)
