I'm guessing VERY mediocre. I'm judging from Phyllis Gardner; it's very unlikely she was an outlier in that department as far as what she thought of EH. You wanna bet ALL the women professors had the same opinion? Women see through EH in a flash lol; it's the guys who don't.
Phyllis Gardner (pictured), a professor of medicine at Stanford, criticized Elizabeth Holmes' blood testing company long before fraud charges were brought against her.

The most telling symptom of someone who doesn't do well in elite education, and EH was not destined for success at Stanford:
"She didn’t listen. She came with these ideas and she would not listen..." You've got to be able to listen and interact with other people's ideas to get a degree: that's pretty much what higher education is about, and HUGELY what elite higher ed is about. And EH wasn't listening to anyone.
So, yeah, getting a college degree even in prison could be a challenge, but if her husband leaves her and she has to make a living after prison, she'd better buckle down.
