Accurate punctuation is the quickest way to raise your technical accuracy mark in Section B writing, and weak sentence control can cap an otherwise strong response. In AQA 8700 and similar boards, this is assessed mainly through AO6 in the 40-mark writing task, while sentence forms can also be commented on in reading analysis.
By the end you’ll be able to
Demarcate sentences securely with no comma splices or run-on sentences
Use commas correctly in lists, after fronted clauses, around parenthesis and in direct speech
Use semicolons, colons, dashes, brackets, ellipses and exclamation marks accurately and for deliberate effect
Use apostrophes for possession and omission correctly, and punctuate dialogue and quotations accurately
What the exam asks
In GCSE English Language, punctuation and sentence demarcation are not usually tested in a separate question. Instead, the examiner judges whether you can:
control sentence boundaries securely
use a range of punctuation accurately
choose punctuation deliberately for clarity and effect
punctuate dialogue and quotations correctly
avoid basic technical errors that damage fluency
For AQA, this matters most in:
Paper 1, Section B: descriptive or narrative writing
Paper 2, Section B: viewpoint or transactional writing
A technically secure script usually has:
Feature
What examiners notice
Clear sentence boundaries
No run-ons or comma splices

Range
Some semicolons, colons, dashes or brackets used accurately where appropriate
Control for effect

exclamation mark: Stop!
You can also join closely linked ideas with:
