I think you (generic you) use every advantage that you have (ethically, of course). Whether that’s natural inborn talent or affinity for a certain skill area (music, math, art, athletics), whether that’s family resources at your disposal, or whether that’s anything else.
I think it’s the very definition of smart to leverage what you have available to you.
When my twins were in high school, they often took the same class but in different periods. They’d sit independently in their rooms and struggle with a problem and I’d say - look, you guys have each other. Why not work together and leverage the fact that your twin is right here with you to talk through and solve the problem? I suppose that’s “leveraging an unfair advantage” but I don’t see a thing wrong with it. If one’s parent is a mathematician, scientist, historian, whatever, is that “unfair” to talk to one’s parent to get help in a certain area? I’m not talking about having Dad the Scientist do your science fair project, but I see nothing wrong with leveraging available resources.
