What is "swap classes" and how does it work?

Swapping classes allows you to “trade” one class for another without giving up your seat in the original class until your enrollment in the new class is confirmed. In contrast, when you drop a class and then add another as two separate transactions, you risk not having a seat in either class.

You can generally swap any two classes (if you meet the prerequisites for the new class) online during the registration periods and dates published in the Registration Calendar. However, be careful with corequisite lecture and lab courses. You'll need to satisfy the paired enrollment requirement as follows:

• If a lecture class permits any class section of a corequisite lab, you may swap either the lecture or the lab for another section of the same course (e.g., BIOL 100 or BIOL 100L). This will satisfy the enrollment requirement.
• If you are taking a grouped CHEM 101 lecture and discussion, you cannot swap the lecture or discussion components. However, you can swap the CHEM 101L lab because any class section of the corequisite lab is permitted (the five-digit class section numbers do not matter).
• You cannot swap corequisite courses if they are linked at the class section level. That is, the two corequisite courses have been paired using their specific five-digit class section numbers. You must enroll in the prescribed class sections.

Always look at the Class Notes section of Class Search to learn if specific sections have been paired. Refer to Course requisites on this page.

I can’t find an open class that I really need. What should I do?

Sometimes you can’t get the classes you want, so here are some strategies:

• Wait list for closed classes. If a seat opens up, you might be added.
  Helpful: Wait List for Closed Classes Guide
• Attend a class for the first week or so and ask the professor to give you a permission number to add. Though there is no guarantee you’ll be added, participate as if you were enrolled. If you persist and other students drop, you might be added.
• Consider taking a CSU Fully Online Course, a program that allows eligible CSU students to take one fully-online, asynchronous class per semester at any other CSU campus at no additional charge.
• Ask your academic advisor to suggest additional ideas and to advocate on your behalf if necessary.
• For the future, add your priority classes first as soon as your enrollment appointment arrives. Use the Registration Planner lock courses feature to plan the rest of your schedule around your priority classes.

A class I enrolled in has disappeared from my schedule. What happened?

A class missing from your schedule in the ¼ªÏé·» Portal may have been cancelled. Normally, the department will email you when a class is cancelled.

To confirm that the class has been cancelled, go to Class Search (no login required) and look up the missing course. On the Search Results page, click the Detail icon. The Class Status field should display "Cancelled.”

You can also contact the to confirm the class was cancelled. Be sure to tell them the five-digit class section number.

What are course requisites?

Course requisites are requirements or conditions that must be met before you can enroll in a class. If you haven’t met the requisites, you won’t be able to add the class. Take a moment to understand requisites.

Types of Requisites

• Prerequisite: A course that is required before you can take another course. For example, you must first successfully complete French 101 (or its equivalent) before you can enroll in French 102. The SOLAR registration system checks student records to ensure prerequisites have been met.
• Corequisite: Two or more classes must be taken concurrently. For example, the lecture BIOL 106 must be taken concurrently with the related lab BIOL 106L. To enroll successfully, place both corequisites, the lecture and the lab, into your cart before submitting your request.
• Conditions can be pre- and corequisites. These may include class level (e.g., junior standing), a specific exam score, a specified passing grade, etc. For example, enrolling in CHEM 101/L (lecture and lab) requires a satisfactory score on the Chemistry Placement Test or a grade of C or higher in CHEM 100 taken at ¼ªÏé·» only.

Find details in the University Catalog entry .

Where can I find the requisites for a course?

You'll find course requisites in several places:

• In the .
• In the registration tools Class Search, Registration Planner and the online self-service Add Classes module. Any requisites will display in the “Class Notes,” “Course Description” and “Enrollment Information” sections of these tools.

How do I enroll in corequisite courses?

Notice How Corequisites are Linked

You must always take corequisite courses concurrently and place both classes into your enrollment shopping cart before submitting your request. Be sure to match the correct pair of corequisites to avoid the "Requisites Not Met" error!

Many corequisite courses allow you to enroll in any combination of lecture + lab class sections. The five-digit class section numbers do not matter.

• Example: As long as you place any section of BIOL 101 lecture and BIOL 101L lab into your enrollment cart at the same time, your request to add will succeed.

When corequisites are linked section-to-section, you’ll need to pay attention to the five-digit class section numbers. You must pair specific lecture + lab class section numbers to enroll.

• Example: Five sections of ME 186/L: Mechanical Design I and Lab are offered. As indicated in "Class Notes," if you choose the ME 186 lecture class section #15994, you must also enroll in the ME 186L lab section #15995. Place this pair of class sections into your cart before submitting your request.

Tips & Tools to Enroll in Corequisites

Use your registration tools to notice which corequisites to add.

• Class Search: Look up a course and select the Detail icon link for one of the class sections. Read the “Class Notes” section to check whether to enroll in any corequisite section or a prescribed section. If a specific section number is provided, write down the five-digit class numbers of the two courses you need to take concurrently. Now you're set to add the correct pair to your cart.
• : Select both corequisite courses before exporting a favorite schedule to your enrollment cart. You can run the Registration Planner validate schedule feature to check for corequisites.
• In self-service Add Classes, always review the "Enrollment Preferences" page shown in the image below. This example confirms that BIOL 101 requires concurrent enrollment in any section of the BIOL 101L. Place the corequisite lecture and lab sections into your cart before you finish enrolling.

What is an enrollment appointment?

All matriculated ¼ªÏé·» students (i.e., those enrolled in ¼ªÏé·» degree or certificate programs) receive an enrollment appointment each fall and spring semester. Your personal enrollment appointment is the earliest date and time that you can register for fall or spring classes. You may continue to add classes and adjust your schedule thereafter, until access to the online self-service registration system ends. Find exact dates at Registration Calendar.

Where can I find my enrollment appointment?

View your appointment in your ¼ªÏé·» Portal Checklist. Your enrollment appointment will display several weeks before it’s time to register. Helpful: My ¼ªÏé·» Portal Checklist Guide

When is my enrollment appointment?

For fall and spring enrollment, ¼ªÏé·» students receive a designated appointment. The Office of the Registrar will email you a "registration notice" several weeks before enrollment begins as a reminder to prepare.

For summer classes, ¼ªÏé·» students "self-appoint" a time to register on a first-come, first-served basis. Helpful: Enroll in Summer Classes Guide

How is my appointment determined?

¼ªÏé·» students are assigned a fall and spring enrollment appointment based on their class level, the number of units completed at the time appointments are produced, and other factors. Seniors must apply to graduate to receive an earlier appointment. Did you know? Your completed number of units displays in your DPR audit.

Can I change my appointment?

Registration appointments are not negotiable. Plan ahead, enroll in priority classes first, use Registration Planner to fit classes into your schedule, and wait list for classes as needed. Helpful links:

• Degree Planning Tools

Can I register before my enrollment appointment?

No. You must wait until your registration appointment day and time for access to the “Add Classes” pages through your ¼ªÏé·» Portal and the SOLAR Student Center.

My friend and I are both seniors, so why did he get a different registration date than I did?

Seniors who’ve applied for graduation have priority over those who have not. Registration appointments are prioritized; every student is assigned a time based on class level, number of completed units at the time appointments are produced, and other factors.

When are final exams?

Final exams are held during the week following the last day of formal instruction. Note that the last day of classes differs for weekday and weekend classes.

• Fall and Spring Semesters: Find exact dates in the Registration Calendar.
• Summer Term: Final exams are held on the last class meeting. Confirm date and time with your instructor.

You should refer to your personal final exam schedule in the ¼ªÏé·» Portal and verify it with your professors, but a general overview of the final exam schedule is published below in PDF:

• Spring 2025 Final Exam Schedule Overview (PDF)
• Fall 2025 Final Exam Schedule Overview (PDF)

Where can I find my final exam schedule?

Your current-semester final exam schedule displays in the . From the top navigation Academics menu, select My Classes and then Current Class/Exam Schedule. For a tutorial, visit View Final Exam Schedule.

• After the fifth week of classes, revisit your final exam schedule in the portal to check for updates.
• A few weeks before your last class meeting, ask your instructor or the academic department to confirm your final exam schedule.

If you see any time conflicts or other issues with your exam schedule, resolve them as soon as possible before final exam week begins.

What if I can't attend a final exam?

Bring any final exam time conflicts or other issues to the attention of your instructor as soon as you notice them and before final exams week begins.

• If a time conflict occurs for the final exams between any two courses, contact both instructors immediately so they can help you resolve it.
• If you cannot attend a scheduled final, contact your instructor to arrange to take the exam at another time, request a or find another solution.

Please review the .

What is a permission number and how do I use it?

Permission numbers allow students to register in specific classes that they would not otherwise be able to enroll in. You will need a permission number to:

• Enroll in restricted classes* at all times, even before classes begin
• Wait-list for restricted classes during the wait list period
• Enroll in all classes starting with Week 2 of spring and fall instruction (i.e., as soon as the waitlist period ends)
• Enroll in state-funded, year-round cohort courses during summer terms

*Restricted classes are usually limited to certain student groups such as freshmen or seniors, majors, and credential candidates.

If a class is restricted, the “Notes” section of Class Search will display "Department/Instructor Consent Required" (refer to image below).

How to Use a Permission Number

Enter the permission number on the “Enrollment Preferences” page in the registration system. (For help, review the guide Add Classes and the image below.) Please note:

1. If the class is restricted, you will see "Department/Instructor Consent Required" in the Enrollment Information section.
2. Check “Class Notes.” If concurrent enrollment in a co-requisite class is required, obtain a permission number for each class before proceeding.
3. Enter the number into the “Permission Nbr” box and proofread it!
4. Select the "Next" button to proceed.

A permission number can be used for a specific class until:

• Your enrollment in the class is successful, or
• Access to the online registration system ends, or
• The permission number expires on an earlier date specified by the department or instructor.

When are permission numbers required?

Permission numbers are always required to enroll in:

1. Restricted classes (e.g., those limited to certain student groups such as freshmen or seniors, majors, and credential candidates) offered in any term or semester, and
2. Year-round, state-funded cohort programs offered during summer term.

During the fall and spring semesters, permission is required to add all classes starting with the second week of classes.

Where can I get a permission number?

Request permission to enroll in a class from the academic department or the professor as follows:

• Before classes begin, you can usually obtain a permission number from the academic department.
• When classes begin, you should attend the class and request a permission number from the professor (in most cases).

I got a permission number to add a class, but it isn’t working. What do I do?

First, make sure you’ve correctly entered the permission number in the registration system. If so, then the number may not be working because:

• You have a registration hold. To view holds, log in to the ¼ªÏé·» Portal and locate the hold message in your Checklist. Resolve the hold and try the permission number again.
• You have a . The registration system does not permit enrollment in two or more classes whose times overlap even by a minute.
• You are attempting to enroll in more than the .
• You’re already enrolled in the class or you’ve already taken it in a prior term.
• You're already on the waitlist for the course, or the course is in your enrollment cart.
• The permission number may have expired. All permissions expire when access to online, self-service registration ends; some permissions expire earlier. Contact the for assistance.

A permission number works only with its associated class section. If the class requires concurrent enrollment in another class (a co-requisite class), obtain a separate permission number for each class before enrolling.

If you've tried all of the above solutions and none work, please contact Records and Registration.

How do I know if I have holds that will block my registration?

Log in to your ¼ªÏé·» Portal. In the Checklist, find the Incomplete Tasks section and look for registration holds.

What is the Measles/Rubella hold? Why is it preventing me from registering?

Students born on or after January 1, 1957 are required to provide proof of immunization for, or immunity against, measles and rubella during their first semester at ¼ªÏé·». Students age 18 or younger must provide proof of immunization for, or immunity to, Hepatitis B during their second semester. Generally, this information can be found on your high school transcript.

Note: You must clear immunization holds before you can register in future semesters.

For more information and updates, visit Immunization Requirements, or contact the Klotz Student Health Center at (818) 677-3666 or shcinfo@csun.edu.

I already met with my advisor but have a hold saying I need to meet with my advisor, and now I can't enroll. What do I do?

Contact your academic advising center to verify that the hold will be removed. You may need some follow-up advisement. Only your advisor can remove an advising hold, not Records & Registration.

Find your center at University Advising.

I have a previously disqualified hold, and now I can't enroll. Why won't it go away?

Good news—it’s not the kind of hold that will prevent you from enrolling. However, it is a reminder of disqualification.

Each time you are disqualified, the rules change for readmission to the University. After the third disqualification, the student must wait 5 years before reapplying to ¼ªÏé·» and taking classes, including those offered through The Tseng College (Extended Learning).

Ask your advisor for guidance. Learn more at .

I have a hold for missing transcripts, but I sent them to ¼ªÏé·» last semester. Why won't the registration system let me enroll?

Chances are you were enrolled in some classes at the other school when you submitted the transcripts. If so, then you did not have grades awarded for those in-progress classes, and the transcript you submitted was preliminary.

We need your final grades; otherwise, you’ll get a missing transcript hold placed on your account, which will prevent you from enrolling. If you feel you’ve received the hold in error, contact one of the following offices:

• To check if ¼ªÏé·» has received your transcript, contact Records and Registration at (818) 677-3800, complete our Contact the Registrar web form, or visit us in the Bayramian Hall Student Services Center.
• To learn why ¼ªÏé·» needs the missing transcript, contact the Office of Admissions at (818) 677-3400, email admissions@csun.edu, or drop by Bayramian Hall Room 160 during business hours.

If you are sending us a final transcript from a California community college, save time with eTranscript California.

When can I repeat a course?

You may repeat a course previously taken at ¼ªÏé·» when Nonrestrictive Registration begins (no enrollment appointment is needed). For specific dates, refer to the Registration Calendar.

During the fall and spring semesters, a permission number is required to enroll in all classes beginning with the second week of instruction, as soon as the wait listing period has ended.

Before deciding to repeat a course, consult your academic advisor and review the following policies based on your class level:

What is Title IX and why is the training required?

Title IX of the Education Amendments of 1972, together with other federal and state laws, protects all people from sexual harassment, violence and discrimination on the basis of gender or sexual orientation. It’s also your right to review safety plans and crime statistics for a college campus. Learn more at Your Right to Know: Student Consumer Information.

All ¼ªÏé·» students — and college students throughout the United States — are required to take an online, interactive sexual misconduct, violence awareness and prevention video course to promote a culture of respect.

How do I take Title IX training?

During your ¼ªÏé·» studies, you'll need to complete the "Title IX" course as follows:

• New students take the initial, longer “Not Anymore” course once only, before enrolling in first-semester classes.
• Continuing students take the short “Every Choice” refresher course once a year, before enrolling in fall classes.

Log in to the ¼ªÏé·» Portal and look for the "T9" registration hold (if any) in the Checklist under Incomplete Tasks. Visit the tutorial or login directly:

• Access Title IX Training How-To Guide

What if I don't take Title IX training?

All students will have a "Title IX (T9)" registration hold. You must complete the online video course before you can enroll in classes.

Are there alternatives to taking Title IX training?

We understand that the content of the training may cause particular distress for some individuals. If due to such personal circumstances you would like to discuss alternative options for meeting the training requirement, please contact ¼ªÏé·»’s Campus Care Advocate, a confidential resource, at (818) 677-7492.
