The Goal Key is created and assigned by your school, and it is usually associated with a specific class or test you are taking. Unfortunately, this means we here at EdReady do not know it; your school has to provide you with the correct key for your particular situation.
Here are some suggestions to locate the key:
1) Check the instructions for EdReady that were provided by your school; they should include the key.
2) Contact your teacher, advisor, testing center, etc. -- whoever told you to use EdReady.
Please note that the Goal Key is not the same as your account activation code and is never sent to you by email from EdReady. It is ONLY given out by the school.
