How to Show Working and Stop Losing Method Marks

This is the study-habit companion to our full guide on how 0606 marking works, that page explains the M/A/B system; this one is about training the habits day-to-day until they’re automatic under exam pressure.

The five habits

1. One step per line, working downward. Never chain three manipulations across one line. Vertical working is auditable, by the examiner (who awards what they can find) and by you (checking is scanning, not re-deriving). This habit alone catches arithmetic slips before they propagate.

2. Formula first, numbers second. Write the general statement, the quotient rule, the discriminant, the chain for connected rates, then the substituted version. The general line is routinely the method mark, and it forces your brain to commit to a method before the arithmetic starts.

3. Name the defining equation. $\frac{dy}{dx} = 0$. $b^2 - 4ac < 0$. $|2x - 1| = \pm(x + 3)$. These single written lines are marks; computed silently they are nothing.

4. Exact values until the last line. Fractions, surds, $\pi$ and ln-forms all the way down; round once, at the end, to what the question asks. Mid-working rounding is the quietest mark leak in the subject.

5. Finish with a sentence when the question asked a question. “Determine whether…”, “Show that the ships meet”, “Explain why $f$ has an inverse”, the final mark wants words: “Since … , therefore …”. Train the reflex: question in words, answer in words.

How to train them (two weeks)

Take questions you can already do, that’s important; the habits won’t form while you’re also fighting new content. For two weeks, solve ten familiar questions per day under one rule: write for a stranger who must reconstruct your reasoning from the page alone. Mark your own working against the real scheme, counting method marks separately. Days 1–3 feel slow and silly. By day 10 the habits run at normal speed, and they hold under exam pressure because they were drilled, not remembered.

The homework test

Here’s the uncomfortable check for self-studiers: show this week’s working to someone who hasn’t seen the questions. If they can’t follow your solutions without your commentary, neither can the examiner, and the examiner won’t ask. This is also the honest argument for having working marked externally every week: bad habits are invisible to their owner. It’s the core of what happens in our 1-to-1 classes.
