I had the same thought so I checked [1]. Really very odd graphs of both male and female students. I haven't seen anything that really explains the peaky total number let alone the ratio profile. Interestingly the higher degrees seem to be pretty stable in ratio terms. Not sure what they may be indicative of though. Very strange.
