How to join a class

Join a class

1. Get the class code from your instructor (a short code like k7m4qp), or a direct join link that looks like /c/k7m4qp.
2. If you have a link, just open it. Otherwise go to the join page, type the code into the box, and select Join class.
3. You'll land on the class page showing your instructor's latest code snippets.

View & copy snippets

• The newest snippet appears at the top, labelled Latest. The page keeps the 10 most recent, so you can catch up if you joined late.
• Your instructor may give a snippet a short title (e.g. Exercise 3: binary search), shown above the code. Snippets without one just show the time they were shared.
• Your instructor may pin one snippet, marked Pinned. It stays at the very top no matter how many new snippets arrive, so it's usually the task or reference you need for the whole class.
• The page updates automatically — when your instructor shares something new, it shows up without you needing to refresh.
• Your instructor can also correct a snippet they already shared. It stays where it is in the list and picks up an Edited marker, so if you copied that snippet earlier, copy it again to get the fix.
• Select the Copy button on a snippet, then paste it into your editor. Indentation, tabs, and blank lines are kept exactly as the instructor pasted them, so whitespace-sensitive languages like Python stay correct.
• Code is colour-highlighted when your instructor tags its language. The colours are for reading only — Copy always gives you the plain original text. Long lines scroll sideways within the snippet box; plain-text notes wrap instead.
• When your instructor shares a link, select it to open it in a new tab — this page stays open behind it, so you won't miss the next snippet. Copy still gives you the plain address.
• Notes your instructor writes in Markdown arrive formatted — headings, lists, tables and links. Copy gives you the plain text behind the formatting.

Light or dark

• Select the round button in the bottom-right corner of any page to switch between light and dark. It starts out matching your device's own setting, and remembers your choice on this browser afterwards.

Troubleshooting

• “Not found” page? Double-check the code with your instructor — codes are all lowercase and don't contain the letters o, i, or l (to avoid confusion with zero and one).
• Nothing new showing up? Check your internet connection, then reload the page — it will re-load the latest snippets and reconnect for live updates.
