Course Planning:

• Please take a look at theÌýAES Curriculum, which lists the courses required for the degree.
• If you have additional questions, please contact your advisor.
• You may also run a Degree Audit within to view your remaining degree requirements. More information on how to do so is available from the Registrar's Office Degree Planning website.

Enrolling in Courses:

• Current students: You can find your enrollment window listed in your around the time midterms happen each semester. Follow the steps listed on the Registrar's Office Registration website to access your enrollment start date/time.
  • If you are an ASEN student, please make sure you enroll as soon as your enrollment window opens as this will give you the best opportunity to enroll in your selected courses and sections. 
• Incoming students: Please refer to the academic calendar.
• Non-ASEN students: The Aerospace Advisors and Curriculum Team can only assist with enrollments into ASEN courses. Please visit this site for more information on requesting enrollment in CEAS courses not listed with the ASEN prefix. Registration in ASEN courses is not guaranteed.

Swapping classes or sections:

Use the Swap option to change classes or sections (if the new section is open). More information about how to use this option can be found here.

ASEN 4018 & ASEN 4028 Senior Projects course enrollment:

In the Fall semester, you can enroll into an ASEN 4018 Senior Projects team of your choice. During the first week of the Spring enrollment period, you will automatically be enrolled in your team section of ASEN 4028 unless there are account holds, time conflicts, or maximum credit limit issues.Ìý

Enrolling in graduate ASEN courses:

• If you are in the ASEN BAM program, you can self-enroll in graduate ASEN courses.
• If you are not in the ASEN BAM program or not in the College of Engineering, you must obtain permission from the course instructor. Upon instructor approval, please forward the approval email toÌýaes-enrollment-help@colorado.edu along with your SID, course number, and section number you are requesting enrollment into.

Enrolling in non-ASEN courses within the College of Engineering:

The Aerospace Advisors and Curriculum Team can only assist with enrollments into ASEN courses. Please visit this site for more information on requesting enrollment in CEAS courses not listed as ASEN.

Enrollment Errors:

Prerequisites or co-requisites:ÌýÌý

A prerequisite course is a course that you must complete before enrolling in another course or program. Prerequisites ensure that you have the necessary knowledge and skills to succeed in the subsequent course.

A co-requisite course is a course that must be taken at the same time as another course. You must enroll in co-requisite courses at the same time.ÌýYou cannot enroll in one without the other.ÌýThe knowledge gained in a co-requisite course complements the knowledge gained in the other course.

If you have questions about meeting prerequisite or co-requisite requirements, please meet with your academic advisor.

Time conflicts:

It is your responsibility to create a schedule with courses that are required to complete your degree. A hard time conflict is one that cannot be avoided between two required courses in an academic year. If you have a time conflict with any of your courses, contact each of the instructors requesting permission to be enrolled with the time conflict. You will also need to talk about making up any missed time/work. Forward the approval emails to AES-Enrollment-Help@colorado.edu and the department will enroll you.

It is important that prior to doing so you have looked at all scheduling options and have ensured there is no way to avoid the conflict. Please work with your academic advisor to determine if other options might be available.

Account Holds:

This information is available in After logging in, follow the steps on the Registrar's Office Holds website to access information specific to your hold and how to clear it.

If it is a Bursar's Office hold (i.e. unpaid balances, etc.) contact them - they often will lift the hold for 24 hours so you can register for classes. Other holds usually need some sort of resolution before they can be lifted. Your academic advisor can provide help with those.Ìý

Waitlists:

Waitlists are a mechanism to help the department assess demand for a course and can be added or removed at any time to support the enrollment process. Not all ASEN courses have a waitlist.

If there is a waitlist and you meet the enrollment requisites, you can add yourself to the course waitlist.ÌýDirections on how to waitlist can be found here.

Being on a waitlist for a course does not guarantee your enrollment in that particular section. We strongly encourage you to enroll in an alternative course or an open section, if applicable, as soon as possible before the add deadline. Your academic advisor can help you review your options. While we do our best to accommodate waitlisted students, it is safer to assume you will likely not get into a waitlisted class and you should plan ahead accordingly, especially in cases where it would affect your full-time student status or graduation date.

Please know the entire Aerospace Department –

• Has your best interest in mind.
• Will ensure you can take the required core ASEN courses you need to stay on track with a four-year plan.
• Recognizes enrollment priorities and will account for this information when processing requests.
• Will guarantee you will be able to take the courses you need.

The Department cannot guarantee preferred schedules or accommodate extracurricular activities, work, or minor course conflicts.

Closed Courses:

Some courses have very strict room and/or lab equipment capacities. Enrollment caps may be incrementally increased throughout the enrollment period to ensureÌýsufficient resources are availableÌýfor all students. If a course you need in order to stay on track for graduation is closed for more than a week and a waitlist or alternative section is not available, please contact your academic advisor for help.Ìý

Dropping Classes:

You are able to drop classes on your own, if it's not tied to a co-requisite course requirement. Be sure to talk with your advisor before you drop to ensure dropping the course(s) will not negatively impact your academic plan.
