We bet on the change agents within the universities. And so, various universities come to us and say, We have some ideas about completion rates, here are some things we want to try out, it's actually budget that holds us back from being able to do that. People come to us and say, We want to try a hybrid course where some piece is online, some piece is not, and we're aiming this at the students that are in the most need, not just the most elite. So that's who we're giving grants to, people who are trying out new things in universities. Now the idea that if you have a few universities that figure out how to do things well. how do you spread these best practices, that's a tough challenge. It's not the quite same way as in the private sector that if somebody's doing something better, the price signals force that to be adopted broadly. Here, things move very slowly even if they are an improvement.
