If you refuse Jade she is gonna fume a bit and threaten to fail you, nothing much else happens in the rest of the story. Yeah she doesn't like you, but who cares? If her paths remain closed only the future can tell.
If you opened the Jade path, we can't tell if Jade will be a problem for Maya's tuition or if it would help, it might be just a problem for MC if he dumped her at the end of chapter 8, we just don't know...
Besides that the tuition from Burke can go everywhere, most optimistic he says yes and that's it, happy ending, but that's an anticlimax to the story so highly unlikely, so expect a no from Burke and either some blackmail from Jade for the MC or a Quinn that whispers Maya the suggestion she might get it afterall if she does the nasty with Burke...
Whatever happens it most likely will end in exposing Burke, that much seems logical.... But it may be at the end of season 4.
