Late Change Petition: Withdrawing from a Course after the Deadline

To withdraw from a course after the withdrawal deadline has passed, approval of the instructor and the associate dean are required via the Change of Schedule form. 

Students withdrawing from all classes in a term (fall or spring) may do so online by the last day of classes, prior to finals.

Approval for withdrawing from a course after the withdrawal deadline has passed requires documented proof of extenuating circumstances. Poor academic performance is not an acceptable reason for a Change of Schedule after the withdrawal deadline. 

No exceptions are made to the published deadlines. After the deadline to submit a Late Change Petition has passed, you may consider a complete withdrawal. The College strongly recommends that you meet with your academic adviser first to discuss options.

Important Note: Withdrawal deadlines vary depending on the term and session.


Exceeding 19 Units

The maximum number of units allowed in fall and spring semesters is determined by the college in which you are enrolled. The College of Engineering adheres to the maximum number of units allowed by the University of Arizona and across the Arizona University System. The maximum number of units include all work carried in residence as well as concurrent registration in correspondence, extension or approved courses at other institutions.

Academic Criteria

Once sophomores, juniors and seniors have established a substantive track record of academic achievement, they may be permitted an exception to exceed the 19-unit limit if they meet the following academic criteria:

  • Students with Advanced Standing have a cumulative GPA of at least 3.0.
  • Students with Advanced Standing, but who are completing course deficiencies, have a cumulative GPA of at least 3.50.
  • Students without Advanced Standing have a cumulative GPA of at least 3.50.

As a policy, the College does not grant first-year students permission to take more than 19 units of coursework per semester.

Submission Process

Send an email to, from your CatMail Student Email account.  Include your Student ID number, the term in which you want to increase your unit limit, and the total number of units for which you intend to enroll.

Please note that a request to go more than three units over the 19-unit limit will require a meeting with the associate dean for approval.


Students who do not meet the academic criteria for exceeding 19 units but feel they have a compelling reason to justify an exception must submit the following documentation for consideration:

  • A paragraph stating the reason for the request and an academic plan for managing the additional course load.
    Taking extra courses to graduate sooner is not a basis on which the College will grant an exception to the University’s 19-unit maximum.
  • A brief statement from your academic adviser supporting your petition.
  • A current copy of your unofficial transcript.

Submit your packet to The associate dean will determine whether a meeting with the student is required.
