The portal stops you cold with a message saying you have exceeded the maximum allowed units. For students trying to catch up on carryovers or push ahead faster, this cap can feel like it is standing in your way for no reason, especially when you have already planned your semester around those extra courses.
Understanding why the limit exists, and how to work around it properly, saves you from fighting a system that is not actually broken, and it puts you in a far stronger position when you eventually sit down with your course adviser to make your case.

Why the unit cap exists
Universities set a maximum number of credit units a student can register per semester to protect academic performance. Taking on too many courses at once can affect your ability to study properly for each one, so the cap is meant to be a safety measure, not a punishment aimed at slowing you down.
The specific number allowed usually depends on your faculty, your level, and your current cumulative grade point average, which means two students in different departments can have completely different caps even within the same session.
How an overload waiver works
A waiver simply means getting special permission to register more units than the standard cap allows, and it is a recognised process rather than something you have to beg for informally.
- Speak to your course adviser first, since they usually need to approve the request before it goes further.
- Prepare a clear reason, such as needing to clear outstanding carryover courses before graduation.
- Submit a formal request through your department, following whatever format they require.
- Wait for approval before attempting to register the extra units again on the portal.
Having a clean academic record for your other courses, aside from the carryovers you are trying to clear, strengthens your case considerably when the request lands on your adviser’s desk. Attaching a brief written explanation along with your result transcript, rather than just a verbal request, often makes the process move faster since the department has something concrete to reference when approving the extra load.
What to keep in mind
Not every request for an overload gets approved, especially if your current academic standing is weak. A strong CGPA improves your chances significantly, since departments are naturally more comfortable approving extra workload for students who have shown they can handle a full course load well already.
Where to find your faculty’s specific unit cap
Every faculty publishes its own course registration guidelines, usually available through the main UNILAG portal reachable via unilag.edu.ng, and your specific department’s student handbook is the most reliable place to confirm exactly how many units your level is permitted to register in a normal semester before an overload becomes necessary. Relying on what a classmate from a different faculty tells you can be misleading, since caps genuinely differ between faculties such as sciences, arts, and engineering, each of which structures its credit load differently based on the nature of its coursework.
Planning your overload request around the academic calendar
Submitting your overload request as early as possible in the registration period, rather than waiting until the deadline is closing in, gives your course adviser and department more breathing room to process the paperwork properly. Departments handling a large number of simultaneous requests close to a deadline often move slower simply because of volume, so getting ahead of that rush by starting the moment registration opens puts your own request near the front of the queue rather than buried somewhere in the middle of a last minute pile.
If your request does get declined for a specific semester, ask your adviser directly whether reapplying the following semester, once your CGPA has had a chance to improve, would carry a better chance of success. Many students find that a single semester of consistently strong performance is often enough to change an adviser’s initial hesitation into approval the next time around.
Conclusion
An overload waiver exists precisely for situations like carryovers or students trying to graduate on schedule, so hitting the unit cap is not a dead end. Approach your course adviser early, make your case clearly, and keep your academic record in good shape, since that combination gives you the best possible chance of getting the extra units approved before registration closes. Treat the process as a normal part of registration rather than an exception you have to fight for, and start it the moment you realise you will need the extra units, not after the deadline is already breathing down your neck.
Frequently Asked Questions
Quick answers to common questions about this guide
1Is an overload waiver guaranteed once I apply?
No, it depends on your department’s internal rules and your academic standing at the time of the request.
2Can I request an overload every semester?
It varies by department. Some allow it regularly for students clearing carryovers, others restrict it more tightly.
3Does a low CGPA automatically disqualify me?
It makes approval harder but does not always disqualify you outright. Speak with your course adviser about your specific situation.
4How long does the waiver approval process take?
It depends on how quickly your department processes the request, so start early rather than waiting until registration is about to close.
