If you are trying to log into GradPoint/Connexus, and are unable to, this is most likely happening because you have gone over your number of allowed absences for the quarter. Here's what to do next:
Contact your teacher to discuss the situation.
Complete an elective credit.
Once your account has been reactivated, complete extra assessments to return your attendance to good standing.
If your account is deactivated more than once during a quarter, you will need to wait until the start of the next quarter to continue. No need to reapply. Contact your teacher for more details.
