How do I know if my teacher graded my homework?

After you have entered your email on the Student Portal, you will receive a confirmation and a grade once the teacher has completed grading your assignments.  In addition to the email you will receive showing your grade, you can always check your Student Portal which is updated on the hour, located on this site which is immediately updated.  Remember, never use Apex to check any grades or due dates as CUSD weights many activities and does not require work to be completed on holidays or weekends.  This is why you need to use the Student Portal to check grades and due dates, NEVER use Apex. 

You should have entered your email address and cell number the first time you logged into the student portal.  If you haven't done that you should do so immediately.
