SPaG — the 16 marks you can't afford to leave on the table

AO6 is worth 16 marks across each writing task. That's the difference between a 4 and a 6, or a 6 and an 8. Examiners aren't looking for perfection — they're looking for range plus accuracy. Range means showing you can use a variety of structures and punctuation; accuracy means doing it correctly.

The marking bands in plain English

• Top band (5–6 marks per chunk): wide range of vocabulary, deliberate variety of sentence structures, accurate punctuation including ambitious choices (semicolon, colon, dash, parenthesis), few errors.
• Mid band (3–4): mostly accurate full stops and commas, some sentence variety, mostly correct spelling, occasional errors.
• Bottom band (1–2): errors interfere with meaning; sentence structure repetitive; punctuation limited.

So: to climb the bands, show range and stay accurate.

Sentence variety — the spine of AO6

A high-band paragraph mixes:

• Simple sentences (one independent clause).
• Compound sentences (two clauses joined by a coordinating conjunction).
• Complex sentences (main clause + subordinate clause).
• Fragments (deliberate, for emphasis).

Annotated example:

"I waited. (Simple — punchy opener.) The clock above the desk had stopped, although I noticed only when the second hand failed to twitch. (Complex — main clause + 'although' subordinate clause.) I tapped the desk, watched the door, listened. (Compound with serial commas, then asyndetic fragment-like list.) Nothing. (Minor sentence — emphasis.)"

Four sentence types in five sentences. That paragraph almost certainly scores in the top AO6 band before the examiner even checks the spelling.

Punctuation — what the top-band uses

Comma — the workhorse

Use commas to:

• Separate items in a list (after each except the last).
• Mark off subordinate clauses ("After the rain stopped, we walked on.").
• Bracket parenthetical phrases ("My mother, who rarely visits, arrived early.").
• Separate independent clauses joined by but / and / so (in long sentences).

Semicolon — the link between equals

Use a semicolon to join two independent clauses that are closely related and could each stand alone:

"I waited; the clock did not move."

It's the punctuation of consequence, contrast, or echo. Strong examiner indicator.

Colon — the gatekeeper

Use a colon when the second part explains or lists what the first part promises:

"There was only one thing left to try: I called her." "He brought everything he'd need: a torch, a knife, a length of rope."

Dash — the pause with attitude

A dash is a more dramatic comma, used for:

• Sudden change of direction ("I knocked — and the door opened on its own.").
• Parenthesis with weight ("The deputy manager — who had run the centre for thirteen years — said nothing.").
• Emphasis on a final phrase ("And then there was silence — total, absolute silence.").

Apostrophe — the most-failed punctuation in GCSE

Two uses:

• Contraction: don't, won't, it's (= it is). Replace the missing letter with the apostrophe.
• Possession: the dog's lead (one dog), the dogs' leads (multiple dogs). Singular = before the s; plural = after.

The most common mistake: its / it's. Its (no apostrophe) = belonging to it. It's (apostrophe) = it is. If you can't replace it with it is, you don't need the apostrophe.

Spelling — the high-frequency errors

Words students misspell most often (and how to nail them):

• definitely (de-FIN-itely — fin in the middle, like the end of a fish).
• necessary (one c, two s, like a necessary cardigan).
• separate (there's a rat in separate).
• embarrassed (two rs, two ss — embarrassment doubled).
• occasionally (two cs, one s).
• environment (the n you forget — environ-MENT).
• government (an n you also forget — govern-MENT).
• received (i before e, except after c — but check; English breaks this often).
• their / there / they're — possession / place / they are.
• your / you're — possession / you are.
• affect / effect — affect is a verb (the rain affected the match); effect is usually a noun (the effect was disastrous).

Common SPaG errors

• Comma splice — joining two complete sentences with only a comma. ("I waited, the clock did not move.") Use a semicolon or full stop.
• Run-on sentence — three or four clauses joined with "and" or no punctuation. Break it.
• Misplaced apostrophe — possessive its with an apostrophe.
• Capitalisation slip — proper nouns (places, names) without capitals.
• Tense slip — switching from past to present mid-sentence.

How to gain marks fast in revision

In the last 5 minutes of Q5:

1. Re-read each sentence aloud (in your head).
2. Check every its — replace with it is and see if it still works.
3. Check every comma joining what looks like two sentences.
4. Check that you used at least one semicolon, one colon, and one dash.
5. Pick one over-used word ("very", "really", "nice") and replace it.

That five-minute pass alone can move you up a band.
