Random Challenge of the Day #35

There was a time in college, We had this lecturer who was very strict, and he was unpredictable. No one was able to predict what he was going to do in every class, so everyone tried their possible best not to miss his course because it was a major course. When exams came, i read so much for his course more than any other couse and i was very confident that i was going to clear the papers. Immediately the exam papers were shared, i discovered that he brought out things more advanced than we thought. Out of 100, i could not answer up to 10. So i decided to do the guess game, i had not gone far when i heard "Everybody drop your pen". I cried my way down to the hostel. I was sure with what i wrote, if there is anything worse than an F, i should get that..LOL.. But thank God i had a C, I was very excited that i did not repeat the course.
