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 retailer is affected by load-shedding, a new competitor and low staff morale. Classify each by business environment and state the level of control.
In other words — as if you have never seen this before
If you have never seen this before: Micro: full control; market: some control; macro: no control. 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?
Three challenges.
3. Which method — and why this one?
Micro: full control; market: some control; macro: no control.
4. Step-by-step working
01 / 07
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.
02 / 07
Step B — Write the given in a column
Three challenges.
Why this step: A column with units stops you mixing cm with m, or minutes with seconds. Markers can also see you started correctly.
03 / 07
Step C — Name the method in words
Micro: full control; market: some control; macro: no control.
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.
04 / 07
Identify the given
Staff morale — micro (full control). New competitor — market (some influence). Load-shedding — macro (no control).
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.
05 / 07
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.
06 / 07
Step F — Box the answer with its unit
Micro, market and macro respectively.
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.
07 / 07
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
Micro, market and macro respectively.
Copy onto your answer sheet — in this order
Answer: Micro, market and macro respectively.
6. Check it like a marker
Strategy differs by control.
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…”
