How we got there
Read this like a teacher at the board. We go slowly, name every number, and say why we take each step.

1. What is the question asking?
Read the question twice. Circle the unknown. Underline every number and unit. The paper is asking: Case study: A manager hires his cousin without advertising the post. Explain why this is unprofessional.
Before any working — hunt first
Given
Numbers and units already in the sentence: no numbers yet — only a name, a diagram, or a worded unknown. Copy each one into a column. A name without a number is not given.
Missing
After you copy the given, the letter that still has no number is missing. The paper is pointing at: Explain why this is unprofessional. Circle that word — that is the missing variable.
Find
We are required to find: Explain why this is unprofessional. Write that as a symbol on the left, with a question mark, before you touch a formula.
Calculate
What we need to calculate: Fair recruitment. Then substitute the given, one line at a time, to get Explain why this is unprofessional.
In other words — as if you have never seen this before
If you have never seen this before: Fair recruitment. We will name a method in words, write the formula with no numbers, then substitute one line at a time.
2. What do we already know?
Nepotism.
3. Which method — and why this one?
Fair recruitment.
4. Step-by-step working
01 / 08
Step A — Read the question twice
Slow down. Circle the word that names the unknown. Underline every number and its unit. Do not grab a formula yet — first decide what the paper is actually asking.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.

Step A2 — Hunt: Given, Missing, Find, Calculate
Given: Numbers and units already in the sentence: no numbers yet — only a name, a diagram, or a worded unknown. Copy each one into a column. A name without a number is not given. Missing: After you copy the given, the letter that still has no number is missing. The paper is pointing at: Explain why this is unprofessional. Circle that word — that is the missing variable. Find: We are required to find: Explain why this is unprofessional. Write that as a symbol on the left, with a question mark, before you touch a formula. Calculate: What we need to calculate: Fair recruitment. Then substitute the given, one line at a time, to get Explain why this is unprofessional.
Why this step: Do not name the letters yet. First hunt: what already has a number (Given), what has no number (Missing), the word the paper wants (Find), and which formula still contains the missing letter (Calculate).

Step B — Write the given in a column
Nepotism.
Why this step: A column with units stops you mixing cm with m, or minutes with seconds. Markers can also see you started correctly.
04 / 08
Step C — Name the method in words
Fair recruitment.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
05 / 08
Explain
Nepotism: unfair, may hire less qualified person, lowers staff morale, may breach EEA.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
06 / 08
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
07 / 08
Step F — Box the answer with its unit
Unfair nepotism.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
08 / 08
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.
5. The answer
Unfair nepotism.
Copy onto your answer sheet — in this order
Answer: Unfair nepotism.
6. Check it like a marker
Advertise posts and use panels.
7. A trap first-timers fall into
First-timers often grab the first formula they remember, mix units (cm with m, minutes with seconds), or drop a minus sign. Write the formula in words first: “this equals that, because…”
