A class key looks like this: A123-bc45, it is made up of letters and numbers. If the key you have doesn’t work, please:
- Check you are typing it exactly as it was given to you. Codes are case-sensitive (so you must copy capital and lower case letters as they are shown in your code)
- Make sure you are not adding any spaces (especially at the beginning or end of the code)
- If the problem continues, please ask your teacher for help.
