The other exam reminded me of the Engineering Electromagnetics exam we wrote in our 3rd semester under grad. 10 minutes into the exam, most students started looking around the class with silly smiles. The whole exam was a "problem paper" as opposed to the tradionally expected "theory paper". We were caught off-guard, ambushed. Then began the process of putting together, whatever BS we could and throw it into that answer paper. The same thing happened recently. We stared into this thing called the "question paper" and didn't have a clue what was going one. Heads turned around and smiles were exchanged as if to say "what the hell...". Then the 2 hours looked like a long marathon. I was guilty to get up and leave. I felt the compulsion write whatever I could thnk of. So every minute looked like an hour. I waited for the clock to finally turn over and the invigilator say "time up".
Exams are funny!
