Accuracy: sentences, punctuation and SPaG

A big chunk of the writing marks in GCSE English Language is for technical accuracy — spelling, punctuation and grammar (SPaG), plus varied and correct sentences. You can lift your grade just by writing accurately.

Use a range of sentence types

  • Simple sentence: one main idea. The rain fell.
  • Compound sentence: two ideas joined by a conjunction (and, but, so). The rain fell and the streets flooded.
  • Complex sentence: a main clause + a subordinate clause. Although it was late, she kept working.

Varying these shows control and keeps writing interesting.

Punctuation to use accurately

  • Full stops, capital letters — every sentence.
  • Commas — lists, after openers, around extra information (not to join two full sentences — that's a comma splice).
  • Apostrophes — contraction (don't) and possession (Sam's).
  • Higher-level punctuation used correctly impresses: semicolons (join linked sentences), colons (introduce), dashes (add emphasis), brackets (add extra detail).

Spelling

  • Learn common tricky words (necessary, separate, definitely, because).
  • Apply spelling rules (drop the silent e, double the consonant, i before e).

Paragraphing

  • Start a new paragraph for a new idea, time, place or speaker.
  • Use discourse markers (firstly, however, in addition, finally) to link paragraphs.

Proofreading

Always leave 5 minutes to check:

  • Homophones (its/it's, there/their/they're).
  • Missing capital letters or full stops.
  • Sentences that are too long or run on.

Worked example

Weak: it was late everyone was tired they went home.

Accurate: It was late, and everyone was tired; they went home. (Capital letters, comma, semicolon joining linked ideas.) ✓

Common mistakes

  • Comma splices (joining full sentences with a comma).
  • Mixing up homophones and misusing apostrophes.
  • Writing one long paragraph with no breaks.

Exam tips

  • Deliberately use a range of sentence types and some higher-level punctuation.
  • Paragraph clearly and link with discourse markers.
  • Proofread for SPaG at the end — easy marks.

Quick recap

  • Vary simple, compound and complex sentences; punctuate accurately (avoid comma splices).
  • Use higher-level punctuation (semicolons, colons, dashes) correctly to impress.
  • Paragraph for each new idea and proofread for SPaG.
