Apologies for double email. I was wondering if you could share with me the numerical constraints and if it would be possible to work a way around it. If it is a classroom size problem, I can sit out and follow the course from my classmates notes. If it is a hardware problem, I can probably provide my own. If it is an exercise grading problem, perhaps I can find an already existing exercise group willing to take me in. I can be flexible if some nonstandard ways of participation are possible. Unfortunately, I expect to graduate soon and likely won't have the chance to take a similar course later on. Hence my plea.
