I ran the club in the University of Waterloo for my undergrad. Do not bring guns on campus. It's an extremely sensitive thing and could risk your education.
Store them offsite if you can. It's not about your knowledge of gun safety or whatever "for your age". Universities generally don't want anything resembling a weapon on campus. Even for events like Humans Vs Zombies in campus they did not want painted nerf guns to give you some perspective.
