1Solve for x: x^2 - 5x + 6 = 0.
A.x = 2 or x = 3
B.x = -2 or x = -3
C.x = 1 or x = 6
D.x = -1 or x = -6
Explanation: Factorise: x^2 - 5x + 6 = (x - 2)(x - 3) = 0, so x = 2 or x = 3. The two roots multiply to give +6 and add to give +5, matching the equation when written with a leading minus on the x-term.
2Solve for x using the quadratic formula: 2x^2 - 4x - 3 = 0 (round to two decimal places).
A.x = 1.58 or x = -0.58
B.x = 2.58 or x = -0.58
C.x = 2.00 or x = -1.50
D.x = 0.58 or x = -2.58
Explanation: Using x = (-b +/- sqrt(b^2 - 4ac)) / 2a with a = 2, b = -4, c = -3: discriminant = 16 + 24 = 40, sqrt(40) ≈ 6.32. x = (4 +/- 6.32) / 4, giving x ≈ 2.58 or x ≈ -0.58.
3For which values of k will the equation x^2 + kx + 4 = 0 have equal (real) roots?
A.k = +/-2
B.k = +/-8
C.k = +/-4
D.k = +/-16
Explanation: Equal roots occur when the discriminant b^2 - 4ac = 0. Here k^2 - 4(1)(4) = 0, so k^2 = 16 and k = +/-4. A zero discriminant gives one repeated real root.
4Solve the inequality: x^2 - x - 6 < 0.
A.x < -2 or x > 3
B.-3 < x < 2
C.x < -3 or x > 2
D.-2 < x < 3
Explanation: Factorise: (x - 3)(x + 2) < 0. The roots are x = -2 and x = 3. A product is negative between the roots, so the solution is -2 < x < 3.
5Simplify: (2^(x+1) . 2^(x-1)) / 4^x.
A.2
B.1
C.4
D.2^(2x)
Explanation: The numerator is 2^(x+1+x-1) = 2^(2x). The denominator 4^x = (2^2)^x = 2^(2x). So 2^(2x) / 2^(2x) = 2^0 = 1.
6Solve for x: 3^(x) = 81.
A.x = 3
B.x = 27
C.x = 4
D.x = 9
Explanation: Write 81 as a power of 3: 81 = 3^4. Since the bases are equal, the exponents are equal, so x = 4.
7Solve for x: sqrt(x + 7) = x - 5 (consider only valid solutions).
A.x = 2
B.x = 2 or x = 9
C.x = -2
D.x = 9
Explanation: Square both sides: x + 7 = x^2 - 10x + 25, so x^2 - 11x + 18 = 0, giving (x - 2)(x - 9) = 0. Test both: x = 2 gives sqrt(9) = 3 but x - 5 = -3 (rejected); x = 9 gives sqrt(16) = 4 = 9 - 5 (valid). Only x = 9 works.
8Solve simultaneously: y = x + 1 and x^2 + y^2 = 25. Which is one valid solution pair?
A.(3, 4)
B.(4, 3)
C.(5, 0)
D.(0, 5)
Explanation: Substitute y = x + 1 into x^2 + y^2 = 25: x^2 + (x+1)^2 = 25, so 2x^2 + 2x - 24 = 0, x^2 + x - 12 = 0, giving (x+4)(x-3) = 0. For x = 3, y = 4, so (3, 4) is valid and satisfies both equations.
9Determine the 20th term of the arithmetic sequence: 5, 9, 13, 17, ...
A.85
B.77
C.81
D.80
Explanation: The first term a = 5 and common difference d = 4. Using T_n = a + (n - 1)d: T_20 = 5 + 19(4) = 5 + 76 = 81.
10Find the sum of the first 15 terms of the arithmetic series 3 + 7 + 11 + ...
A.450
B.480
C.435
D.465
Explanation: Here a = 3, d = 4, n = 15. Using S_n = n/2 [2a + (n-1)d]: S_15 = 15/2 [6 + 14(4)] = 7.5 (62) = 465.

About the NSC Mathematics Exam

NSC Mathematics is the Grade 12 exit examination written under South Africa's CAPS curriculum and administered by the Department of Basic Education (independent schools may use the IEB or SACAI), with Umalusi providing quality assurance. Candidates write two externally set and marked papers, each worth 150 marks over 3 hours. Paper 1 covers algebra and equations, number patterns and series, functions and graphs, finance/growth and decay, differential calculus, and probability. Paper 2 covers Euclidean geometry, analytical (coordinate) geometry, trigonometry, and statistics with regression. The final subject mark combines a 75% external examination with a 25% internally set, externally moderated school-based assessment, and results are reported on a 7-level achievement scale.

NSC Mathematics Study Tips from Top Performers

1Split your revision between Paper 1 (algebra and calculus) and Paper 2 (geometry, trig and statistics) so neither half is neglected.
2Memorise the standard formulae on the information sheet, but practise applying them in past-paper style problems rather than just reciting them.
3Drill the Euclidean geometry theorems and acceptable reasons, since geometry carries 50 of the 300 marks and rewards precise proof writing.
4Master special-angle values and reduction formulae in trigonometry before attempting 2D and 3D application questions.
5Work timed Paper 1 and Paper 2 mocks (3 hours each) to build exam stamina and accurate calculator use.
6Always check whether interest or depreciation is compound or simple, and whether compounding is monthly or annual, before applying finance formulae.

Frequently Asked Questions

How many papers does NSC Mathematics have and how long are they?

Two external papers, Paper 1 and Paper 2, each worth 150 marks and written over 3 hours. Paper 1 focuses on algebra and calculus, while Paper 2 covers geometry, trigonometry and statistics, for a combined 300 marks.

What is the pass mark for NSC Mathematics?

The minimum subject pass is Achievement Level 2, which is 30-39%. To use Mathematics for a Bachelor's or Diploma pass and university entry, learners generally need higher levels (40% or more), and competitive programmes expect 60% and above.

How is NSC Mathematics graded?

Results are reported on a 7-level achievement scale: Level 7 (80-100%, Outstanding), Level 6 (70-79%), Level 5 (60-69%), Level 4 (50-59%), Level 3 (40-49%), Level 2 (30-39%) and Level 1 (0-29%). Umalusi may apply standardisation adjustments across years.

What topics are in Paper 1 versus Paper 2?

Paper 1 covers algebra and equations, patterns and sequences, functions and graphs, finance/growth and decay, differential calculus, and probability. Paper 2 covers Euclidean geometry, analytical geometry, trigonometry, and statistics with regression.

Who sets and quality-assures the NSC Mathematics exam?

The Department of Basic Education sets the public-school papers (independent schools may use the IEB or SACAI), and Umalusi quality-assures the National Senior Certificate, which sits at NQF Level 4.

Does the final mark only come from the exam?

No. The final subject mark is 75% from the two external papers and 25% from school-based assessment (SBA), which is internally set and marked but externally moderated.
