NOTE: SAP must be done in person, and there will be plenty of time to do this in person once the campus resumes its normal activities.
1. You should start the SAP appeal form now, by reading through the information here (http://financialaid.arizona.edu/managing-my-aid/satisfactory-academic-progress-sap-policy). You can start writing your personal statement and collecting appropriate documentation. This will facilitate the in-person meeting with your Academic Advisor in January.
2. Make an appointment with your academic advisor.  If math is your primary (or only) major, you may request an appointment here:  http://math.arizona.edu/academics/undergrads/advising/appointments

Please watch for an appointment confirmation from mcenter@math.arizona.edu.
