In "A Christmas Carol", Dickens presents the idea of redemption through Scrooge. Dickens allows the reader to envision a change in attitude through this charactor by highlighting his refusal to change. Soon turned into many actions, this is percieved at the beginning of the novel and this extract. This is when Marley warns Scrooge to listen to him through the quotes "I wear the chains I forged in life" and "Hear me!". The use of punctuation highlights a sence of urgency towards the situation through the exclamation mark. The order "Hear me" tells the reader that Scrooge needs to change and how Dickens uses the figure of his best friend to influnce Scrooge. Furthermore, the ghost of Marley acts as a catalyst for Scrooge's transformation. His appearance is described as terrifying, wrapped in chains that symbolise the consequences of greed and selfishness. Through this encounter, Dickens suggests that it is never too late for reedmption, a message that would have resonated deeply with his Victorian audience who valued charity and moral responsibility.
- Feedback pinned to the sentence it refers to, not dumped at the end.
- Graded on your mark scheme — GCSE, A-Level, KS3, BTEC, Functional Skills.
- Spelling flagged, and counted only if your criteria score it.
1 Simplify 5a + 3a − 2a
= 6a
2 (a) Solve 3x + 5 = 20
3x = 20 − 5
3x = 15
x = 5
2 (b) Expand and simplify (x + 3)(x − 2)
= x² + 3x − 2x − 6
3 Work out 2⁄3 + 1⁄4
= 8⁄12 + 3⁄12
= 11⁄12
4 Find 15% of £240
10% = 24
5% = 12
= £36

Built for trust.
Designed for GDPR.
Handling student data is a serious responsibility. We've architected GradeOrbit from the ground up to minimize data exposure and maximize privacy protection.
The protections below apply to individual accounts. School accounts work differently by design — student work is retained under a Data Processing Agreement so teachers can return to results. See how school accounts handle data. Want to know who is behind it? Read about the team building GradeOrbit.
Zero student data retention on individual accounts, encrypted in transit and at rest, and full UK DPA / GDPR compliance.
Built-in Redaction Tools
On individual accounts, you draw redaction boxes directly on student work to permanently black out names, addresses, or any personal information before AI processing. The redaction is "burnt in" — the original data is never sent to our servers.
Zero Data Retention
On individual accounts, we never store uploaded student work. Images are sent to Google's Gemini API for analysis, under terms that rule out training on them, then gone once your session ends — never saved to our database. Your students' work stays ephemeral and protected.
Anonymous by Design
On individual accounts, students are identified only as "Student 1", "Student 2", and so on. We never attempt to detect, store, or process student names or identifying information.
