Scotland's National 5 Mathematics (C847 75) is a SCQF Level 5 qualification, assessed by a 40-mark non-calculator Paper 1 (1h 15min) and a 50-mark calculator Paper 2 (1h 50min). Awarded by Qualifications Scotland (formerly SQA) with grades A-D, A-C is a pass.

Sample National 5 Mathematics Practice Questions

1Simplify sqrt(12) + sqrt(27).
A.5*sqrt(3)
B.sqrt(39)
C.6*sqrt(3)
D.5*sqrt(6)
Explanation: sqrt(12) = sqrt(4*3) = 2*sqrt(3) and sqrt(27) = sqrt(9*3) = 3*sqrt(3). Adding gives 2*sqrt(3) + 3*sqrt(3) = 5*sqrt(3).
2Rationalise the denominator: 10 / sqrt(5).
A.2*sqrt(5)
B.sqrt(50)
C.10*sqrt(5)/5
D.sqrt(2)
Explanation: Multiply top and bottom by sqrt(5): 10*sqrt(5) / 5 = 2*sqrt(5). The rationalised form is 2*sqrt(5).
3Simplify sqrt(8) * sqrt(6).
A.4*sqrt(3)
B.sqrt(48)
C.2*sqrt(12)
D.sqrt(14)
Explanation: sqrt(8)*sqrt(6) = sqrt(48) = sqrt(16*3) = 4*sqrt(3). Always reduce surds to simplest form.
4Simplify (2x^3)^4.
A.16x^12
B.8x^12
C.16x^7
D.2x^12
Explanation: Raise each factor to the power 4: 2^4 = 16 and (x^3)^4 = x^(3*4) = x^12. Result: 16x^12.
5Evaluate 16^(3/4).
A.8
B.12
C.4
D.64
Explanation: 16^(3/4) = (16^(1/4))^3 = 2^3 = 8. The denominator gives the root and the numerator gives the power.
6Simplify x^(-2) * x^5.
A.x^3
B.x^(-10)
C.x^7
D.1/x^3
Explanation: When multiplying powers with the same base, add the exponents: -2 + 5 = 3. So x^(-2) * x^5 = x^3.
7Write 0.000043 in scientific notation.
A.4.3 x 10^(-5)
B.4.3 x 10^(-4)
C.43 x 10^(-6)
D.4.3 x 10^5
Explanation: Move the decimal point 5 places to the right to get 4.3, giving 4.3 x 10^(-5). The number is less than 1 so the index is negative.
8Calculate (3 x 10^4) x (2 x 10^6) and write the answer in scientific notation.
A.6 x 10^10
B.6 x 10^24
C.5 x 10^10
D.6 x 10^11
Explanation: Multiply the numbers and add the indices: 3 x 2 = 6 and 10^4 x 10^6 = 10^(4+6) = 10^10. So the answer is 6 x 10^10.
9Simplify (x^5 * x^2) / x^3.
A.x^4
B.x^10/3
C.x^0
D.x^(10/3)
Explanation: Multiply: x^5 * x^2 = x^7. Divide by x^3: x^(7-3) = x^4. Add indices when multiplying and subtract when dividing.
10Express sqrt(45) - sqrt(20) in simplest surd form.
A.sqrt(5)
B.5*sqrt(5)
C.sqrt(25)
D.sqrt(5)/2
Explanation: sqrt(45) = 3*sqrt(5) and sqrt(20) = 2*sqrt(5). Subtracting: 3*sqrt(5) - 2*sqrt(5) = sqrt(5).

About the National 5 Mathematics Exam

National 5 Mathematics (course code C847 75) is the standard Scottish qualification at SCQF Level 5, sat by most candidates in S4. It is awarded by Qualifications Scotland (formerly SQA) and covers three subject areas: Expressions and Formulae, Relationships, and Applications. Assessment is by two written papers — Paper 1 (non-calculator, 40 marks) and Paper 2 (calculator allowed, 50 marks).

Exam sponsor: Qualifications Scotland (formerly SQA). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

National 5 Mathematics: Suggested Study Strategy

1Practise Paper 1 without a calculator — mental arithmetic and fraction handling are heavily tested
2Memorise the exact trig values for 0, 30, 45, 60 and 90 degrees; they are required for non-calculator marks
3Always show full working — even a wrong final answer earns method marks if working is clear
4Use the SQA formulae sheet under exam conditions so you know exactly what is and is not given
5Work through at least the past 5 years of past papers and the marker's commentary published each year

Frequently Asked Questions

Who awards National 5 Mathematics?

National 5 qualifications are awarded by Qualifications Scotland (formerly the Scottish Qualifications Authority, SQA). The body was renamed Qualifications Scotland on 1 February 2026; the course content and structure are unchanged.

How is National 5 Mathematics assessed?

Assessment is by two written papers totalling 90 marks. Paper 1 is non-calculator (40 marks, 1h 15min) and Paper 2 allows a scientific calculator (50 marks, 1h 50min). Both papers test all three subject areas.

What grade do I need to pass National 5 Mathematics?

Grades A, B and C are passes. Grade C requires roughly 50% of the available marks, although grade boundaries are set each year and vary between papers. Grade D is a near-miss and No Award is below that.

When are National 5 Maths exams sat?

The written exams are sat in the May exam diet, alongside the rest of the SQA/Qualifications Scotland diet. Results are released in early August.

Can I use a formula sheet in National 5 Maths?

Yes. Both papers come with a printed formulae list including the sine and cosine rules, area = 1/2 ab sin C, the quadratic formula, volumes of cones/spheres/pyramids, and the standard deviation formula.
