GCSE revision that explains the bit you missed.

As revision starts, practice questions only reveal what’s missing if students understand where the mark was lost. Whether you need targeted help for GCSE Maths, structured feedback for GCSE English, or concept rebuilding for GCSE Science, Leana guides students step by step until it clicks.
From diagnosis to exam practice. Exam boards, subjects and marking claims require verification.
Prototype: verify product capabilities, coverage and outcome claims against the live Leana experience before publication.
● Learning
I know simultaneous equations. Why did I lose the mark?
Your method is right until line three. When you subtracted -4y, which sign did it become?
Positive 4y. I left it negative.
That is the break. Repair that step, then try a new pair without the prompt.
Revision focus: check signed subtraction in a different algebra problem tomorrow.

Diagnose

Find the idea behind the missed mark

Repair

Explain the smallest useful gap

Apply

Return to realistic exam practice

01

A diagnostic starting point

Use current performance to identify high-value gaps instead of treating every topic as equally urgent.
Diagnostic accuracy and coverage must be evidenced.

02

Explanations that branch

Change the wording, example or representation when the first explanation does not click.
Revision should respond to the learner’s misconception.

03

Realistic transfer

Return to exam-style questions after the concept is repaired and reduce support over time.
Do not confuse familiarity with independent performance.

More questions only help when the learner knows what to change.

Leana connects an exam attempt to the underlying concept, then checks whether the learner can use the repaired idea without copying the example.
The repeated lost mark

I revised this topic. Why do I keep making the same mistake?

Another identical worksheet may practise the error. The useful question is where the method first stopped making sense.
A sharper revision loop

Repair the idea, then test it under exam conditions.

Trace the attempt, explain the precise gap, retry without the prompt and revisit it later in mixed practice.

From the difficult moment to a useful next move.

A concrete example makes the promise easier to understand and test.

01

Diagnose

Start with a real attempt.

02

Prioritise

Choose the highest-value gap.

03

Explain

Repair the missed idea.

04

Practise

Use realistic questions.

05

Revisit

Check later recall and transfer.

One clear sequence. No feature soup.

The journey follows the learner’s problem from first attempt to independent use.
For parents

See a plan not revision panic.

Clear priorities

Know which gaps matter most now.

Useful progress

See what became more independent.

Honest uncertainty

Know what still needs a teacher or tutor.

For children

Know exactly what to do next.

Understand the lost mark

Trace it to the first broken step.

Practise with purpose

Use questions selected for a reason.

Build exam independence

Reduce hints and return later.

Before you trust it with learning.

Which GCSE subjects and exam boards are covered?
The final page must name only subjects, qualifications and exam boards verified in the live product. This prototype does not invent coverage.
No grade prediction is promised here. Any future projection would need transparent methodology, sufficient evidence and clear uncertainty.
Marking should follow verified exam-board criteria, show where marks were gained or lost and provide a correction route. Confirm implementation before publishing.
No. Leana is positioned as additional explanation and practice. Teachers and tutors retain essential educational judgement.

Turn the missed mark into the next useful revision step.

Find the underlying gap, repair it clearly and return to a fresh exam-style question with less support.
