For the end of Term, CPS has posted the following for all CPS students logging into Aspen:

Your logon does not have access to Aspen. If you believe you should have access, please contact the Support Desk. Student Logins to Aspen will be disabled from 9:00 a.m. to 6:00 p.m. on January 29th through January 31st to allow teachers to enter and post grades.

So unfortunately, you will have to wait until tonight or next week.  

Thanks for your support of Grade Corner!
