Mathematics N4: where the marks actually are
The first Mathematics subject of the N4–N6 National Diploma ladder, taken at a TVET college over one trimester. It is where the engineering calculus sequence starts.
N4 is being phased out. DHET is closing the NATED Report 191 programmes and replacing them with occupational qualifications. Its teach-out schedule (DHET TVET Circular TC 0134, 24 July 2025) gives the last national N4 examination for Engineering Studies as Trimester 2 2026. The last cohort gets a first sitting in Trimester 1 2026 and one repeat trimester — two chances, not the usual open-ended ones.
This is not a reason to stop. The National N Diploma can still be awarded up to 30 June 2029. Complete before 30 June 2026 and you receive the certificate exactly as now; after it, a DHET Statement of Results, which still counts toward the diploma. The Minister confirmed in June 2026 that qualifications already achieved stay valid and enrolled students should carry on.
Check your own dates with your college. The Department has since issued a revised circular, TC 0134(b), which it has not published, and further extensions were gazetted in June 2026 — so the date above is what DHET last put in writing publicly, not a promise about your intake.
What the exam is worth, module by module
These are DHET's own weight values. The syllabus states that a module's weight value gives the time to be spent teaching it and its share of the marks in the final exam — so this table is, in effect, the mark allocation of your paper. It totals 100.
| Module | Weight | |
|---|---|---|
| Differential Calculus | 25 | |
| Integral Calculus | 25 | |
| Trigonometry | 20 | |
| Complex numbers | 12 | |
| Functions and Graphs | 10 | |
| Determinants | 8 |
How to spend your time
- Half the paper is calculus. Differential and Integral Calculus carry 25 marks each — get those two secure before you spend a second evening on Determinants, which is worth 8.
- Trigonometry at 20 is the third pillar and it feeds directly into the calculus questions, so it pays for itself twice.
- Determinants and Functions and Graphs together are 18 marks. They are the cheapest marks on the paper to secure, but they will not carry you — you cannot pass on them alone.
The syllabus prices the paper at 1 mark = 1.8 minutes. If a question is worth 10 marks and you are 25 minutes in, you are losing marks elsewhere by staying on it.
Getting in
You need one of these:
- Grade 12 Pure Mathematics
- NCV Level 4 Mathematics
- N3 Mathematics
One trimester, full time, part time or distance learning.
How you are assessed
Two things have to go right, and students lose the year on the first one more often than the second.
1. Your college (ICASS) mark
You need at least 40% to qualify to write the final exam at all.
2. The final examination
3 hours, closed book, out of 100 marks, written in April, August, November. You pass at 40%.
- The ICASS trimester mark comes from two formal class tests (or two assignments for distance learners), covering 30% and 70% of the syllabus respectively. Marks stay valid for one year.
- Calculators are allowed. Unless a question says otherwise, round only the final answer, to three decimal places — not during the calculation.
The paper is built to a fixed cognitive split: Remember 20, Understand 20, Apply 20, Analyse 10, Evaluate 20, Create 10 marks per 100. Only 20 marks are pure recall, so memorising worked examples caps you well short of a pass.
