In my experience as a school student there is very little you can do about it beyond making yourself a small target which comes at a fairly high cost. You can make it worse once it happens while being on the receiving end of a wildly hypocritical lecture about how the school "will not tolerate bullying". Standing up to organised group bullying is folly. As an adult you have many more cards to play than that and everyone knows it even if they don't know which cards you have or which of those you're willing to play; the doubt surrounding potential consequences for picking on you counts for something. Precisely none of that improvement in lived experience comes from "learning to deal with it" and "socialization" So that's my experience, others may differ.
