What would you do if you had this teacher?

I have this teacher who is a woman and she is a total [bad word]. We had project presentations and I swear I had the best presentation. Everyone in my cl said they liked mine. My teacher gave me a 0 for creativity and for the overall quality she gave me a 0 which tallied up to 68% F!! Trust me, my work is good! The laziest guy in cl got a 80%. What would you do if you were me?
