A friend of mine did exactly that. Entered U of Waterloo on math scholarship. Lost the scholarship in the first year because of bad grades. Second year transferred from Honirs Math t9 General Math. Third year transferred from Math to film studies. Fourth year transferred from film studies to Independent studies. Fifth year a lot of drinking and soccer - Independent studies did not require any classes just some sort of progress towards some type of essay. I think in sixth year Ontario government cut his student loans. He was on the hook for something like 50,000 CAD. Left to teach English in Seoul. Been there since 2000
