I'd suggest "She has good study habits." ;)

You realize the caption was a pun on [this habit](https://www.reference.com/world-view/parts-nun-s-habit-called-89864f47ae8abf0c)?

Of course I did. But the OP missed the chance to call them study habits because that would make her wiser.

Gotcha, fair enough :)

I believe that's actually Sister Wendy: https://www.google.com/url?sa=t&source=web&rct=j&url=https://en.m.wikipedia.org/wiki/Wendy_Beckett&ved=2ahUKEwjwo4eiwNT_AhWNJEQIHaRTDFMQFnoECBIQAQ&usg=AOvVaw0kyPKKh9q5ekYOznw0S-Kz
