Quick answer

Is Cambridge IGCSE Computer Science (0478) a good fit for high school students in Grades 9-12?

Cambridge IGCSE Computer Science (0478) is a good fit for students in grades 9-12 who are interested in number systems and algorithm design in pseudocode. CIT offers online or in-person lessons in Apgujeong, Gangnam, Seoul, in one-to-one or small-group formats. Students make flowcharts with pseudocode and trace tables, array and file-handling programs, and mock exam answers with an error log by topic.

Theory comes first: binary and hexadecimal conversion and file sizes, data transmission and encryption, the CPU and storage, operating systems, internet security, and automation and AI. Algorithms are written in official Cambridge pseudocode and flowcharts and traced step by step, and array and file-handling programs are written in Python, Visual Basic, or Java. SQL queries and logic circuits come last, followed by a full mock exam that students mark themselves against the criteria. Alongside the score, the student builds the academic evidence an application can use: how they applied a core idea, why an answer failed, and how they revised it.

Current study of, or planned preparation for, Cambridge IGCSE Computer Science (0478).

A short diagnostic review sets the starting point.

Progress depends on regular practice and acting on feedback.

What will my child learn?

  1. Convert between binary, denary, and hexadecimal, and calculate two's complement values and text, image, and sound file sizes.
  2. Explain packet transmission, error detection, encryption, and the fetch-decode-execute cycle step by step.
  3. Decompose problems into official pseudocode and flowcharts, and convert one algorithm between the two forms.
  4. Query a single table with SQL and move between logic expressions, circuits, and truth tables.

How does the course progress?

  1. 1
    Data Representation

    Number base conversion, two's complement, overflow and shifts, and file sizes for text, images, and sound.

  2. 2
    Data Transmission

    Packet switching, serial and parallel transmission, parity and checksum error detection, and symmetric and asymmetric encryption.

  3. 3
    Hardware

    The von Neumann fetch-decode-execute cycle, input and output devices, and RAM, ROM, and secondary storage compared.

  4. 4
    Software

    Operating system resource management, interrupt handling, compilers versus interpreters, and what an IDE provides.

  5. 5
    The Internet and Its Uses

    How a web page loads, digital currency and blockchain, and threats such as phishing and DDoS matched to defenses.

  6. 6
    Automated and Emerging Technologies

    Automated systems and robots evaluated through cases, plus artificial intelligence and the structure of expert systems.

  7. 7
    Algorithm Design and Problem-Solving

    Trace standard algorithms such as linear search and bubble sort in trace tables, and apply validation and verification.

  8. 8
    Programming

    From variables, selection, and loops to arrays, procedures, and file handling, with scenario questions written under time limits.

  9. 9
    Databases

    Design a single-table database with a primary key and field types, and write SELECT, WHERE, and ORDER BY queries.

  10. 10
    Boolean Logic

    Truth tables for each gate in standard symbols, conversion between circuits and logic expressions, and a final mock exam.

What counts as useful evidence?

Flowcharts with pseudocode and trace tables, array and file-handling programs, and mock exam answers with an error log by topic.

What should an admissions reader be able to see?

Alongside the score, the student builds the academic evidence an application can use: how they applied a core idea, why an answer failed, and how they revised it.

Useful evidence may include readable code, tests, version history, design choices, and a working product the student can explain.

The evidence an application reads is what the student understood, completed, and can explain.

Which sources were reviewed?

The official 2026-2028 syllabus has two externally assessed papers. Paper 1 and Paper 2 are each 1 hour 45 minutes, 75 marks and 50%; calculators are not permitted. CIT uses public syllabus and practice material for diagnosis, error correction and explanation. CIT does not write or submit school-assessed work or live exam answers for a student.

Can my child take Cambridge IGCSE Computer Science (0478) online or in person, one-to-one or in a small group?

Yes. CIT offers online and in-person lessons at its Apgujeong academy in Gangnam, Seoul, with one-to-one and small-group options. A readiness consultation confirms the available format and starting point for the course.

Does my child need prior subject knowledge or coding experience for Cambridge IGCSE Computer Science (0478)?

Current study of, or planned preparation for, Cambridge IGCSE Computer Science (0478). A short diagnostic review sets the starting point. Progress depends on regular practice and acting on feedback.

What will my child make or practice in Cambridge IGCSE Computer Science (0478)?

The main evidence is flowcharts with pseudocode and trace tables, array and file-handling programs, and mock exam answers with an error log by topic. Students also document decisions, tests, feedback, and limits in age-appropriate language.

How does Cambridge IGCSE Computer Science (0478) exam preparation work?

CIT starts with a short diagnostic, then works through the units in order, from Data Representation to Boolean Logic, reviewing errors and improving exam-style responses. Practice is adapted to the student's current syllabus and readiness.

How are the schedule and tuition for Cambridge IGCSE Computer Science (0478) determined?

CIT confirms the student's readiness, goal, location, class size, and current availability before recommending a course plan. The consultation and level check are free; tuition is explained before enrollment.

When should a student start?

The exam date is set by the school or the exam board, so the time left decides how many units the student can cover and how much practice fits. CIT checks the remaining weeks first, then proposes a starting unit.

At first my child did not want to go, because it was a weekend class. After the lesson they said it had been fun. Hearing that they ask about anything they do not understand and take part on their own put me at ease as a parent.
