Great contest. My math tutor Mr. Oliver. In Nigeria, we have this thing of taking after school classes or tuitions to prepare for various qualifying exams that most under-grad schools require us to take.

Oliver sir used to take in about 200 kids in four batches of 3-4 2 hr sessions a week. So there were about 50 of us crammed into a small room, some of us in the balcony peering in through the window. I just wish i had taken a photo of the scene to share here.
