OP isn't claiming that that's the case for everyone, but it is the case for some people. There are different contributory skills to academic success, sure.
I happen to have an incredibly retentive memory, a knack for exam technique, a very logical and systems-focused brain, and a huge amount of cultural capital in my personal background.
Put those things together and yes, I was active during revision, but it wasn't work. I ended up doing the exam equivalent of trick shots in my A Levels, quoting bands I liked in English exams, making jokes as part of theoretical arguments, tutoring my friends and inventing revision techniques.
Not the same at all as someone who doesn't know the material beforehand therefore has to learn it before they can think about it, who has to make an effort to remember it, and have to learn exam techniques because though they know the subject well, they don't test well.
While I completely get all this, the OP isn't a school child, she's a 40something mother of three returning to university, far beyond the problems of being perceived as a swot and having teachers who don't like her.
It's very hard to say this without sounding like a twat, but I still do get treated like a swot to a certain extent. I like to talk about philosophy, politics, literary analysis, psychology, history, biology... Even as an adult, you can be on the receiving end of judgement or derision if your main interests aren't all that mainstream.
