Formulae List and Paper Conditions
Use the limited formulae page actively and practise the full course under both non-calculator and calculator conditions.
How to study National 5 Mathematics
Secure one operational skill at a time, connect it to neighbouring techniques, then apply it in unfamiliar contexts with complete working and a checked conclusion.
Core concepts
Concept 1
Paper 1 has 40 marks in one hour without a calculator; Paper 2 has 50 marks in 90 minutes with a calculator permitted.
Exam cue: Annotate a practice formulae page with the structure that triggers each formula.
Concept 2
Both papers supply the same page covering quadratic roots, triangle rules and area, three solid volumes and sample standard deviation.
Exam cue: Practise exact arithmetic, fractions, surds and algebra without a calculator.
Concept 3
All questions are attempted, appropriate working is required for full marks and units should be stated where appropriate.
Exam cue: On Paper 2, use the calculator to support rather than replace a visible method.
Risk pitfalls and guardrails
Assuming every required relationship is printed.
Guardrail: Check signs, brackets, restrictions, units, accuracy and whether the answer needs a reason.
Using a correct formula with mismatched variables or dimensions.
Guardrail: Check signs, brackets, restrictions, units, accuracy and whether the answer needs a reason.
Giving only a calculator display when working is required.
Guardrail: Keep sufficient accuracy through intermediate work and round only the final requested result.
