Coping with a 2 yr composite class

I've always thought composite classes seemed weird. Who has been in one and what was your experience like? Can you give me any tips for success or describe things about working with y0unger or older kids in the same class that worked well for you? Can you advise me on aspects to try to avoid?
Also, please provide me with a list of skills, attitudes and values you think are important to learn and refine over a two year period.
