Don’t just expect to get into Stanford, that school is 100% a reach for just about any student. Judging by the info you’ve given, I don’t think your admission chances are good honestly. If you want to have a chance to get in, aim for near perfect SATs and maybe you’ll have a shot, but you don’t have anything listed that makes you really stand out.
