Dartmouth college (USA), had a requirement that you must pass a swimming test to receive your degree. ( Obviously - if you didn't know how, there were free lessons.)
They have recently dropped that requirement!
( After more than 200 years.)
Why?
At least with the old rules, you always knew that if a person was a Dartmouth grad, you could push them in the water.
Or, at least, not worry about boating with them.
