A few weeks ago, I had an exam. Some of the questions were to be solved by computer and the results printed out and handed in. I didn't do well on the exam: I didn't solve some of the questions and I didn't do the part where I was supposed to print out the results, so I expected to get an F or D but I got a really good grade! Then i went to the professor's office to check my exam i was shocked to see that the papers that I was supposed to print out were "included" and solved correctly!
I was so shocked and nervous I didn't even say a word and left the office! I'm still shocked. I don't know what to do: I don't know if he really helped me or the papers weren't mine and by mistake got included with my papers! And now, when I see him around, I feel awkward. What am I supposed to do?
Shall i go back to his office and tell him i just want to check my grade and leave? Or that i need someone to explain what happened?
