If you are receiving a message that is not listed here, please contact the Registrar's Office at registrar@mines.edu to resolve the issue.

Students are responsible for their course schedules. Please be aware that the Registrar's Office WILL NOT register students for classes unless there is an extenuating circumstance. Students MUST register for all courses online via Trailhead. All registration must be completed online via Trailhead by 5:00 PM on Census Day.


 Message: Closed

Reason: This message will appear when the course is at maximum capacity (full). This means that there are no more seats available in the class for more students to register.

Solution: The student may pick up a Registration Action form from the Registrar's Office, and have the instructor of the course sign to allow him or her to register even though the course is full. Once the form has been completed and returned to the Registrar's Office, the student can register online via Trailhead.

Message: Closed-Waitlisted 

Reason: This message will appear when the course is at maximum capacity (full). This means that there are no more seats available in the class for more students to register. When the "Waitlisted" notation appears, this means that there is a waitlist assigned to the course. This function allows students to add their names to a list so that they can be automatically enrolled once space in the class becomes available.

Solution: The student can add his or her name to the waitlist, and reserve a space in the class should one become available. To do so, look for the drop down menu under "Action" on the registration add error screen. Change the drop-down field to read "Waitlisted On the Web," and submit the changes. This will add the student's name to the waitlist for that course.

NOTE: Students CANNOT use the Registration Action form to enroll in waitlisted classes.

Message: Department Restriction

Reason: This message will appear when a student is attempting to register for a class that is restricted to students whose major is housed within a particular department (different from the student's department).

Solution: The student must either declare his or her major in that department in order to register for classes that are restricted to that department, or obtain a Registration Action form from the Registrar's Office and have the course instructor sign to give permission to register for the course. The student should note on the form that he or she is receiving a Department Restriction Error to ensure that the correct override code (DEPT) is used.

Message: Level Restriction

 Reason: This message may appear when an undergraduate student is attempting to register for a course that is offered at a different level than the student's current level. (For example, an undergraduate trying to register for a graduate (anything 500-level or above) course, or a graduate trying to register for an undergraduate course.) It may also appear when a student is attempting to register for a course that is restricted only to students at a certain grade level. (For example, a sophomore student will receive this message when trying to register for a course that is restricted to senior-level students.)

Solution:

  1. When an undergraduate student wishes to register for graduate-level courses, he or she must come to the Registrar's Office for a 500-Level Course Form. This form must be signed by the course instructor and the student's advisor and returned to the Registrar's Office. The student will need to register him or herself for the class online through Trailhead.
  2. When a graduate student wishes to register for undergraduate-level courses, he or she must contact the Registrar's Office either in person or via e-mail to have the course level overridden. The student must provide the CRN for the class and his or her CWID.
  3. When a student wishes to register for a course that is restricted to students at a certain grade level, he or she must obtain a Registration Action form from the Registrar's Office. This form must be signed by the course instructor and returned to the Registrar's Office. The student should note on the form that he or she is receiving a Level Restriction Message to ensure that the correct override is entered.

 Message: Link Error (This will normally be followed by a number and letter notation. For example, "LINK ERROR - L1 REQUIRED.")

Reason: This message will appear when a student is attempting to register for a course that has a lab, recitation, or studio section attached to it, and only one CRN has been submitted.

Solution: To register for certain classes, both the lecture portion (example: PHGN 100-A) and the lab/recitation/studio portion (example: PHGN 100-SA) must be submitted at the same time. The student must choose one lecture section (this section will always be noted by a single letter) and one lab section (this section will always be two or three letters and/or numbers, like SA or R2 or LHA). Both sections must be selected at once, either by checking both boxes on the Class Search page or by entering both CRNs to the Add & Drop Classes Worksheet on Trailhead. Once both sections are submitted, the registration should be complete.

 Message: Major Restriction or Field of Study Restriction

Reason: This message will appear when a student is attempting to register for a class that is restricted to students with a certain major declared, and that major is different from the one the student has declared.

Solution: The student must either declare his or her major in order to register for classes that are restricted to that major, or obtain a Registration Action form from the Registrar's Office and have the course instructor sign to give permission to register for the course. The student should note on the form that he or she is receiving a Major Restriction Error to ensure that the correct override is used.

Message: Maximum Hours Exceeded

Reason: This message will appear when a student is attempting to register for a class that forces him or her over the maximum credit hour limit. (The normal limits during the Fall and Spring semesters are 19.0 for undergraduate students, and 15.0 for graduate students. For field and summer, the maximum for all students is 12.0 hours.)

Solution: The student must either drop another course from his or her schedule to allow enough hours to register for the new class, or obtain a Registration Action form from the Registrar's Office and have his or her advisor approve an increase to the student's maximum credit hours for that semester. The form must be completed and returned to the Registrar's Office so that the student can register for the additional class or classes via Trailhead.

Message: Open – Reserved for Waitlist

Reason: This message will appear when a student attempts to register for a course where one or more openings have already been offered to waitlisted students, and those waitlisted students are still within the 24-hour window of opportunity to accept those openings. In other words, even though the on-line class schedule appears to indicate that openings exist, those openings are temporarily reserved for currently waitlisted students with the highest priority on the waitlist.

Solution: The student should continue to monitor course enrollment as displayed in the on-line course schedule, and should continue to attempt registration. In the event that a currently waitlisted student does not accept the offer to register, there may be opportunities for another student to add him- or herself to the waitlist.

Message: Prereq & Test Score

Reason: This message may appear because a student is missing one or more of the prerequisites required to enroll in a class (see number 1 below). It may also appear for graduate students who are attempting to register for undergraduate courses (see number 2 below).

Solution:

  1. The student must obtain a Registration Action form from the Registrar's Office. The form must be signed by the instructor of the course, to give the student permission to register without all of the required prerequisites. Once the form has been completed, it must be returned to the Registrar's Office. The student will now be able to register online through Trailhead.
  2. Graduate students do not need clearance signatures from the instructor in order to register for undergraduate classes. Students may either come to the Registrar's Office, or send an e-mail directly from their Mines e-mail account with their name, CWID, and CRN/s of the class/es he or she would like to enroll in. Students will receive an e-mail confirmation once the message has been cleared so that they may register through Trailhead following the normal procedure.

Message: Time Conflict

Reason: This message will appear when a student is attempting to register for a course that either starts or ends at the same time another course starts or ends, or a course that overlaps with another course in which he or she is currently enrolled.

Solution: The student must either drop the course that is conflicting with the new course so that he or she may register, or obtain a Registration Action form from the Registrar's Office. The form must be signed by the instructor of the course in which the student wishes to enroll, not the instructor of the course in which the student is already registered. Once the form is complete, it must be returned to the Registrar's Office. The student will then be able to register online through Trailhead.
