Should I sign in here?
Did your teacher give you a teacher code, username, and password? Then you DO need to sign in to do your work for that teacher.
If your teacher told you to just come here and practice, or if you aren't working with a teacher, you don't need to log in. Try these links instead:
Help — I forgot my password! (...or username or teacher code)
If we have your email address, click "lost your sign-in details?" under the form.
Otherwise, your teacher can tell you the username, password, and teacher code you need to sign in.
