Free GCSE English Language 15-Minute Diagnostic: Find the Marks You’re Losing
A quick, free check-up for Year 10 and Year 11 students. It is designed to identify common weaknesses in GCSE English Language without requiring a full paper.
How to use it
Set a 15-minute timer.
Answer without notes or help.
Check the answers only when the timer ends.
Use the score guide to decide what to practise next.
The diagnostic
1. Language technique
“The corridor swallowed him into darkness.” Name the main technique and explain one effect.
2. Precise inference
“Maya checked the clock for the fourth time and rubbed her palms against her jeans.” What can you infer about Maya? Give evidence.
3. Better analysis
Improve this weak comment: “The writer uses the word ‘cold’ to show it is cold.” Explore a possible connotation of “cold”.
4. Sentence control
Correct the punctuation: Although the rain had stopped the streets were still shining the shops however remained closed
5. Vocabulary
Replace “nice” with a more precise adjective: “The view from the hill was nice.”
6. Structure
A story begins with a crowded station, zooms in on one abandoned suitcase, then ends with the station completely empty. Give one effect of this change.
7. Evaluation
A student says: “The writer makes the storm seem genuinely dangerous.” Give one sentence agreeing or disagreeing and one type of evidence you would look for.
8. Writing
Write one opening sentence for a story called “The Last Train” that creates immediate tension without saying “I was scared”.
Answers and self-marking
1. Personification or metaphor with an accurate effect. Strong answers explain that “swallowed” makes the corridor seem threatening, consuming or inescapable.
2. Maya is likely nervous, anxious or impatient. Evidence includes repeatedly checking the clock or rubbing her palms.
3. Strong analysis explores an implication such as emotional distance, hostility or lifelessness, depending on context.
4. One correct version: “Although the rain had stopped, the streets were still shining; the shops, however, remained closed.”
5. Answers vary. Examples: breathtaking, panoramic, spectacular, tranquil or imposing.
6. Credit an effect such as mystery, unease, isolation or focus on the suitcase.
7. Credit a clear judgement plus relevant evidence such as violent verbs, threatening imagery, short sentences or sensory detail.
8. Credit a controlled opening that creates tension through detail, uncertainty, setting, action or implication.
Score guide
7–8 secure: focus on speed, precision and higher-level interpretation.
5–6 developing well: identify the two weakest question types and practise them deliberately.
3–4 significant gaps: build core analysis, inference and sentence-control skills before doing lots of full papers.
0–2 start with fundamentals and short guided practice.
This diagnostic is a starting point, not a GCSE grade predictor.
