That's basically what my high school did. Students had a lot of flexibility to choose the classes they wanted to take, and had a lot of leeway if they wanted to choose the advanced or standard version of a class. Combine this with a lot of optional classes, and students at my high school could tailor their class schedule to their own needs and wants. I recognize that my experience was no means the norm. My high school was large, well funded, and had a lot of resources at its disposal. And even then, there were absolutely students that weren't served well by the school. But its overall a system that seems to work pretty well, and I think its a model that more schools look at.
