If you are struggling to access Google Classroom using the Wonde login then it might be because your computer / tablet / phone has a personal Google account attached to it. If this is the case you will need to use an incognito window (Google Chrome) or in private browsing (Ipad). Once you have one of those windows loaded up you will be able to log in to Wonde and Google Classroom using the https://edu.wonde.com/login/exwick link. Instructions on how to do this for various browsers are below. Please see alternative blog post if you are using a Chromebook.
