AutoCRN is a helpful Chrome extension developed by lhc70000 that simplifies the course registration process at CityU. This open-source project allows users to fill in and submit Course Registration Numbers (CRNs) automatically, saving them time and effort.

One of the standout features of AutoCRN is its ability to refresh the registration page every 5 minutes, preventing session timeouts and ensuring a smooth registration experience. Additionally, users have the option to set an exact time for the extension to auto-refresh, further streamlining the registration process.

Although the developer has implemented a feature to retry when the page load time exceeds 5 seconds, its effectiveness may vary. Users should also take note of the project's experimental nature and understand that the developer cannot be held responsible for any unforeseen consequences.

AutoCRN is a free Chrome extension that falls under the Browsers category, specifically the Add-ons & Tools subcategory. It is a valuable tool for CityU students looking to simplify and optimize their course registration experience.
