I think the challenge is it's pretty difficult to be customizing instruction to 30 different students at wildly different levels.

Having some students help instruct others can work, and when it works, I think there's a lot of positives. But, it can also be socially akward, and lead to a lot of negatives (especially outside the classroom).

I think there are real issues with equal access to advanced classes, but making it equal by ending the program seems like the wrong thing to do.
