1. I worked for a few years in the remedial math centre for mature students in my university, and one of my best friends did his doctorate in teaching mature students mathematics. Based on my experience, had I taken your attitude then I would have just not shown up for work. 2. I disagree that it doesn't benefit the stronger students. It was awfully hard for me to learn to teach mathematics, because I had never really had to learn it in a step by step way myself. However, when I did learn to teach an area, my understanding was orders of magnitude higher because I had the understanding of somebody gifted in the area but the method and the attention to detail of somebody who has learned it the hard way. If you mix classes with high and low skilled students, you just have to make sure you rely on the high skilled students as a teaching resource.
