Stressed

I am a little stressed right now. I took a test in my history class last Wednesday (the 4th) and was pretty sure I did well. I went to class last night and the professor was mad at how poorly the class had done as a whole. Does this include me, I don't know. He said he wouldn't even hand the tests back until the 16th!!! Why say something like that and then leave us hanging for a week?? I really missed he wouldn't have said anything!
