Online IGCSE Computer Science tutor

Support for Cambridge and Pearson Edexcel IGCSE

International GCSE Computer Science brings together two different skills: explaining how computer systems work and solving problems with algorithms and code. It is common to feel confident in one part and unsure about the other. Lessons can focus on a specific gap or connect the theory and practical work so that each makes more sense.

Cambridge IGCSE and Pearson Edexcel International GCSE are not interchangeable specifications. Bring the exact qualification title, syllabus code and examination year. We check those details before choosing practice questions, terminology and the programming approach. O Level students can also enquire for syllabus-specific Computer Science support.

Turn theory into explanations you can use

A correct definition is a starting point, not the whole answer. We practise applying ideas to a question: for example, explaining why a representation needs a particular number of bits, or relating a system’s components to what it does. You can bring a topic that feels abstract and work through a smaller example before tackling exam-style questions.

• Number systems and data representation, using worked conversions and checks.
• Computer systems, storage and networks, with explanations tied to the specification.
• Algorithms, pseudocode and trace tables where your syllabus requires them.
• Programming, testing and debugging in the language agreed for your course.

Prepare for the right exam year

Exam preparation starts with your current specification, not an old revision checklist. Cambridge publishes different syllabus versions by exam year; future changes should not be applied to students sitting an earlier version. The official links below help you find the right document.

We can work on explaining steps clearly, interpreting command words and checking an algorithm against sample data. Timed practice is useful once the foundations are in place. If you are homeschooled or revising for an October–November sitting, tell us your date and available study time so the plan can prioritise what is realistic.

How your online lessons work

Start with a free introductory lesson to meet Hasan Zeyn, explain what is difficult and discuss your goals. Share your exam board, syllabus code, exam year and a recent piece of work if you have one. That helps us check the qualification match and choose a sensible starting point, rather than assume every student needs the same revision plan.

In paid lessons, explanations are followed by active practice: writing code, tracing algorithms or answering a question together. We look at why an answer works, how to check it and what to practise next. Your tutor can adjust the pace when a prerequisite is missing or move on when you can explain the idea independently.

Lesson times and the online platform are agreed after your enquiry. A computer, reliable internet connection and a way to share your work are useful for programming lessons. Rates, lesson arrangements and any recordings or extra materials are discussed before paid lessons begin. The introductory lesson requires no payment details or commitment.

Meet your Computer Science tutor

Hasan Zeyn is FindTutor’s founding tutor and a Computer Science undergraduate. His teaching covers school-level programming and university computing, with Python, C and C++ among his areas of support. Read his tutor introduction and student feedback, then use the free lesson to check whether his approach suits you.

Progress depends on your starting point, practice and time available. Tutoring supports your learning; it does not guarantee a particular grade, provide exam entry or replace your school’s assessment rules. Independent work and assessed projects must remain your own.

Check your official qualification

Use your exam board’s specification for the year you sit the exam. Topic coverage, permitted notation and assessment arrangements can change. These official pages are reference sources, not endorsements of FindTutor.
