In which I stress out about my physics grade

I was standing outside my physics classroom, waiting to be let inside. One of my classmates walked up and said he couldn't stay, and asked me to turn in his homework for him. I agreed to do it but I thought it was weird because we don't usually have to turn in homework. I looked at the papers that he gave me, and they were already graded by the professor, including a test on Chapter 9. I was confused because the class that I was waiting for was a review class for the Thursday exam on Chpt 4-8. I couldn't remember what I had gotten on my Chpt 9 Exam, so I dug through my backpack and pulled out a test paper with a 29. I was really upset because I couldn't see how I would manage an A in the class if I had gotten a 29 on the test, and I couldn't remember even taking the test.

The professor walked up to me and said that he couldn't stay, but that I should let everyone in and conduct the review session, using a DVD. I knew the DVD was already in the classroom and that it taught physics with the help of little Japanese cartoon animals singing in French. I began singing the song, even though I don't know French, and it sounded like "Sympathique," but it was a different song. I agreed to run the review, but after my professor left it occurred to me that I had no way of letting everyone into the classroom, as it was locked and only the teacher had the key.
