It's likely your campus hasn't modernized their APs, so using 802.11g might be acceptable if they don't offer faster speeds. However, for better compatibility and security, connecting with newer standards would be preferable. This helps maintain a good experience for all users while keeping your connection safe.
It's unusual unless the setup is so bad that signals become very weak. Clients stuck on 802.11g often end up reverting to that standard. Some users on 802.11g don't force others to join, it just wastes bandwidth and drains processing power from the AP as it changes settings constantly.
