The only point I would take issue with is the second part of (e). The current downturn has not affected us much in terms of student throughput because of the Khalifa contract, which has helped to see us through. We are running at near to our maximum capacity.
We have an intentional policy of not increasing class sizes. This is partly because of the normal concerns about instructor-student ratios and partly a matter of sheer logistics - most of our classrooms don't have room for more than 18. We can manage a class of 20, but the room allocation needs a lot of planning. When we had a class of more than 20, there was only one classroom they could use and, anyway, as I said, we didn't feel that they should be disadvantaged compared with everyone else - they were paying the same fees.
So I don't think that the class sizes will ever go above 18 - perhaps 20, at a pinch.
