GCSE English: Spelling, Grammar and Common Errors

Spelling and grammar errors are the cheapest marks lost on any GCSE English Language paper — and the most predictable, because the same small set of confusions accounts for most of them. This quiz targets that set directly, with every question built on original example sentences.

The homophone questions cover the classics that recur in every examiner's report: their/there/they're tested together in a single sentence that uses all three; its/it's, where the possessive takes no apostrophe precisely because "it's" is reserved for the contraction; your/you're; and affect/effect, resolved by the verb/noun test that settles nearly every real case. Each question presents correct and incorrect versions side by side, training the visual discrimination that proofreading depends on.

The grammar questions address the structural errors that mark down otherwise fluent writing: subject-verb agreement where an intervening prepositional phrase tempts the wrong verb ("The box of chocolates is..." — the subject is "box", not "chocolates"), and tense consistency across a sequence of actions — the drift from past to present mid-paragraph that timed writing produces constantly.

The apostrophe questions extend the punctuation set with the possession cases that cause the most trouble: singular possession, and plural possessors ("the students' project", "the ladies' coats") where the apostrophe follows the s. Two usage questions complete the sweep: fewer versus less, decided by countability, and accept versus except.

Each explanation states the underlying rule in one memorable line, making this an efficient final-week revision set: one pass through it, and the ten most common technical-accuracy deductions in English exams each have a rule attached in your memory.

• Use their/there/they're, its/it's and your/you're correctly on sight
• Apply the verb/noun test to choose affect or effect
• Maintain subject-verb agreement past intervening phrases
• Keep verb tense consistent across a passage
• Place possessive apostrophes correctly for singular and plural owners

Skills follow the DfE GCSE English language subject content on spelling, punctuation and grammar — accurate spelling of commonly confused words and grammatical agreement, part of the technical-accuracy component weighted at 20% of the qualification.
