Computer Science Diagnostic

Find the Gaps Before They Cost Marks

Instead of beginning support by guessing what a learner needs, a focused diagnostic identifies the knowledge, programming and exam-technique areas that deserve attention first.

A clearer starting point

Who the Diagnostic Is For

It can help when a learner knows they need support but cannot yet see exactly where the difficulties begin.

  • Topics feel secure in class but test or mock results are uneven.
  • Programming remains difficult despite understanding some theory.
  • Knowledge is present, but marks are lost through exam technique.
  • An important stage of GCSE or A-Level study is approaching.
  • A clear starting point would help before committing to regular tuition.

Focused and practical

How It Works

The exact content is adapted to the learner’s level, course and current needs.

01

Diagnose

Work through carefully selected questions and tasks covering relevant knowledge and skills.

02

Identify

Separate secure understanding from misconceptions and genuine knowledge gaps.

03

Prioritise

Establish which areas deserve attention first instead of revising everything equally.

04

Plan

Clarify practical next steps so future revision or tuition has a sensible direction.

Adapted to the learner

Areas That May Be Checked

The diagnostic focuses only on areas relevant to the learner’s course and current stage.

  • Algorithms
  • Programming
  • Trace Tables
  • Data Representation
  • Computer Systems
  • Networks
  • Cybersecurity
  • Databases
  • Computational Thinking
  • Exam Technique
  • Extended Responses

What becomes clearer

Know What Needs Attention Next

By the end of the lesson, I’ll explain what is secure, where the main gaps or misconceptions are, and what I recommend working on next.

A clearer picture

See which areas are currently secure and where gaps, misconceptions or weaker skills are affecting progress.

Sensible priorities

Understand which topics or skills should be addressed first and what practical next steps would be useful.

Better-informed support

Use the findings as a clearer basis for deciding whether ongoing tuition would help.

No generic starting point

Future support can focus on the learner’s actual needs rather than following a one-size-fits-all sequence.

Two different purposes

Diagnostic Lesson or Ongoing Tuition?

Diagnostic Lesson

  • Establishes the starting point.
  • Identifies gaps and misconceptions.
  • Prioritises what needs attention.

Ongoing Tuition

  • Teaches or reteaches identified areas.
  • Builds skills and confidence over time.
  • Supports revision, programming and exam preparation.

How is this different from the free consultation?

Free consultation: A short conversation to discuss the learner’s needs and whether tuition may be suitable.

Diagnostic Lesson: A paid working session where I assess relevant Computer Science knowledge and skills, identify gaps and misconceptions, and explain the priorities for what to work on next.
