Another option is that his name isn't even Jaune Arc. I mean the way he introduces himself to people in the first few episodes makes it seem like he picked that name instead of just it being his name. I mean when you introduce yourself to someone, do you refer to your name being "Short, sweet, rolls off the tongue" or anything like that?

Maybe he had a friend named Jaune Arc who was an ace student at another school and he allowed Jaune to use his name. Maybe the transcript he claimed were false were actually his and Jaune just copied them and submitted them himself. Of course this just makes everything much more complicated, but it boils down to Jaune maybe having a fake name.
