How to Revise iGCSE ICT

Revise iGCSE ICT with practice on computer systems, communication, data handling, and practical skills.

Revision Strategy

Revising ICT requires a dual approach: learning theoretical concepts and practising practical problem-solving. For theory topics like data representation, networking, and systems architecture, use active recall with flashcards and practice questions. For programming and algorithms, the only effective revision is writing and tracing code.

Practise tracing through algorithms by hand. Exam questions frequently ask you to follow the execution of pseudocode or identify errors in programs. Being able to work through code step by step, tracking variable values in a trace table, is a skill that improves dramatically with practice and is worth a significant number of marks.

Understand the connections between topics. ICT is a subject where concepts build on each other — for example, understanding binary representation helps with data storage, compression, and networking. When revising, actively look for these connections and make sure you can explain how different areas of the subject relate to one another.

Study Tips for iGCSE ICT

✓ Practice using spreadsheet software (formulas, functions, charts, data validation) regularly, as the practical exam requires confident use of these tools under timed conditions.
✓ Learn the theory content systematically - hardware components, network types, security threats and data management. iGCSE ICT theory papers require precise technical knowledge.
✓ Create practice databases and run queries, reports and mail merges to build proficiency with the practical skills tested in the exam.
✓ Study the social, ethical and legal aspects of ICT (data protection, copyright, digital divide, cybersecurity) as these are often tested in extended-answer questions.

Exam Tips for iGCSE ICT

✓ In the practical exam, save your work frequently and follow the naming conventions specified in the question paper. Marks can be lost for incorrectly named files.
✓ For theory questions about the impact of ICT on society, give balanced answers that consider both advantages and disadvantages.
✓ When answering questions about hardware or networks, use specific technical terms and avoid vague descriptions.

Frequently Asked Questions

What is the difference between iGCSE ICT and iGCSE Computer Science? +

ICT focuses on using technology effectively, including practical software skills and understanding the role of ICT in society. Computer Science focuses on how computers work at a deeper level, including programming, algorithms and data representation. ICT is more applied, while Computer Science is more theoretical and technical.

Is there a practical exam in iGCSE ICT? +

Yes. Cambridge iGCSE ICT includes a practical paper where students complete tasks using software applications such as spreadsheets, databases, word processors and web authoring tools. This practical component forms a significant part of the overall grade.

Is iGCSE ICT still relevant with AI and new technology? +

Yes. While specific tools evolve, the principles of data management, digital communication, system design and responsible technology use remain essential. iGCSE ICT provides a foundation of digital skills and understanding that adapts to new technologies.
