Easy. The teacher gave the exact same grade to all my friends and enemies. Oh wait, there are hundreds of other words you can put there. Brilliant question.

This is so easy. Just take out the other people and see what you would say if you were the only person in the sentence. The teacher gave the same grade to I / me. Putting the other people back into the sentence doesn't change a thing.

Me. To figure out which first person pronoun, exclude all the other object and the sentence looks like, "The teacher gave the same grade to me."
