Key steps (method)
- Write down the given information and what you are asked to find for Calculating bearings.
- Choose a representation that fits the topic (diagram / table / algebra / graph) and set it up neatly.
- Bearings are measured clockwise from North and written as 3 digits (e.g. 045°).
- Apply the topic rule(s) step-by-step, showing enough working to keep method marks.
- Substitute values carefully (watch brackets, negatives, and order).
- Write the final answer clearly with correct units/rounding.
- Do a quick check that the answer is sensible for the context.
Common mistakes
- Measuring bearings from the wrong direction (not from North, not clockwise).
- Not using 3 digits (e.g. writing 40° instead of 040°).
- Using the right idea but the wrong rule/interpretation for the topic.
- Skipping key working so method marks can’t be awarded.
- Sign/bracket errors when substituting or rearranging.
- Rounding too early or to the wrong accuracy.
- Not checking whether the answer is reasonable.
