AS & A Level Computer Science (9618) — real past-paper questions, marked by AI
A Level Computer Science (9618) runs from AS theory into A2 problem-solving, where several questions expect a working algorithm written out in pseudocode or high-level code on paper rather than a short verbal answer. Write, state, explain — but also design and trace: the command words shift toward building and testing logic as the papers progress through Papers 1 to 4.
This hub holds 1,501 real 9618 questions from 60 papers set between 2023 and 2025. Algorithm design and problem-solving leads the topic table with 26 questions, ahead of programming, data types and structures, and software development, with floating-point representation and object-oriented programming also well covered. Type your pseudocode or written answer and the AI examiner marks it instantly against the real Cambridge mark scheme, checking each line of logic the way a human examiner traces it.
Sweep algorithm and programming questions by topic before attempting a full A2 paper under timed conditions. It is free, with no signup needed.

Frequently asked questions
Which 9618 papers and years are covered?
Every May–June and October–November session from 2023 to 2025 — 60 papers across Papers 1 to 4 and their variants.
How does the AI marking work for pseudocode and algorithm questions?
You type your pseudocode or high-level code answer, and an AI examiner checks the logic against the official Cambridge mark scheme step by step, showing exactly where it matches or diverges from the accepted solution.
What topics come up most in 9618?
Algorithm design and problem-solving and programming lead the topic count, with data types and structures, software development and object-oriented programming also heavily examined.
What do Papers 1 to 4 cover in 9618?
The papers move from AS theory and problem-solving into A2 practical-style questions answered in pseudocode or high-level code on paper. Revise the component numbers your course enters you for.
Is it really free?
Yes — every question, mark scheme and AI marking run is free, with no signup and no card details.
Are these official Cambridge papers?
Questions are transcribed from real Cambridge papers and marked against the real mark schemes, which remain © Cambridge International. Cambridge Papers is an independent study tool, not affiliated with or endorsed by Cambridge.
