I was undecided as to choosing between two majors and had decided to sit the entrance exams for both subjects. In order to do so, I needed to get a passing grade in thermodynamics. Majīd and I asked one of our friends to tutor us in thermodynamics. He accepted and tutored us for three days. When we got the examination results we saw that Majīd’s grade was four points higher than our tutor’s. The tutor used to kid Majīd, saying, “I taught you everything; how is it that you were able to get a better grade than me?”
