>>12871262as a high schooler having your name on a scientific paper is a big deal. that would be something that could get you into even the most elite schools, provided you emphasize it appropriately on your applications.
OTOH if you don’t actually have a publication and you are trying to hype yourself up then you could easily make yourself very unattractive everywhere. bullshitting on an application is common but making bullshit claims that are easily falsified on google is disqualifying
