All of us are facing the stress of Passing the exam, CET-6, this term, so I am planning a movie night to have some fun. We will watch the movie (Spiderman) in Classroom A001 at 7:00 p.m. on Sun., Sep. 16. If you have any suggestion for the movies, please contact me at 18971393955 before Sep. 15. Hope we have a wonderful night.

I would suggest being informal with your schoolmates. I would also change passing to taking and ask for suggestions about other movies.
