Algorithms finally explained in a way that makes sense

Sorting, searching, pseudocode and trace tables — taught step by step by a GCSE examiner. Clear, calm, no panic.

What this covers

Trace tables broken down line by line
Pseudocode written and explained aloud
Real exam questions with mark scheme thinking
From confused to confident in one session
The problem

Why students struggle with algorithms

😵‍💫
Too abstract
Algorithms are taught as theory first. Most students never see how they connect to real exam questions.
📝
Memorisation without understanding
Students memorise steps without knowing why — then forget them under pressure.
Exam panic
When a trace table appears in the exam, anxiety takes over and learned knowledge disappears.

How I make algorithms click

The same approach that works for every learner I have ever taught — visual first, exam second.

Visual explanations first

Every algorithm is shown visually before any pseudocode. You cannot write what you cannot picture.

Real exam questions throughout

We work through past OCR questions in every session — not textbook exercises. Exam language from day one.

Mark scheme thinking built in

I show exactly what earns marks and what loses them. You leave knowing the difference.

Repetition until confident

Same topic, different questions, until it sticks. No moving on until the last session made sense.

What a session covers

One hour. One algorithm type. Complete understanding.

Trace tables

Step through an algorithm row by row. Understand what each variable holds at each point. The most common exam question type.

Pseudocode

Write pseudocode correctly — OCR syntax, structure, and common pitfalls. Readable by an examiner in under 10 seconds.

Searching algorithms

Linear search and binary search — when to use each, how to trace them, how to explain them in an exam.

Sorting algorithms

Bubble sort and merge sort with full trace table practice. Efficiency comparisons explained simply.

The transformation

What changes after working with Miss ICT

Before
Confused by what an algorithm even is
Guessing on trace table questions
Losing marks on pseudocode every time
Dreading algorithm questions in the exam
After
Clear understanding of what algorithms do and why
Systematic approach to any trace table
Confident pseudocode with correct OCR syntax
Structured, mark-earning answers every time
Why Miss ICT

Taught by a qualified GCSE examiner

Dee has been marking GCSE Computer Science papers and teaching the subject for over 15 years. Every session is shaped by real examiner knowledge — not guesswork.
Marks the actual GCSE Computer Science papers your child will sit
Knows exactly which algorithm questions appear and how they are marked
Has taught algorithms to students from Grade 3 to Grade 9
Adapts explanation style until it genuinely makes sense

For parents

What you can expect

🧘
No pressure, no cold-calling
Sessions move at your learner's pace. If something does not click, we try a different approach. There is no rush.
📋
Clear next steps after every session
Parents receive a brief summary of what was covered and what to consolidate before the next session.
🎯
Focused on exam marks
Every explanation connects back to how OCR marks this topic. No time wasted on things that do not appear in the exam.

Frequently asked questions

Do I need to have studied algorithms at school before this session?

No. Sessions start from where your learner is, not where the syllabus assumes they should be. Complete beginners are very welcome.

How many sessions do students usually need on algorithms?

Most students need two to three sessions to feel genuinely confident — one on searching, one on sorting, and one on mixed exam question practice.

Is this for OCR GCSE only?

Algorithms appear in all GCSE CS specifications. While Dee's examiner experience is OCR-specific, the content is relevant to AQA and Eduqas students too.
