About this course

Learn Cambridge A Level Computer Science 9618 online

Cambridge AS and A Level Computer Science (9618) combines detailed theory with serious programming. Students often struggle with Cambridge pseudocode, writing and tracing algorithms on paper, and the time pressure of the practical Paper 4.

The course follows the official syllabus for exams in 2027, 2028 and 2029. AS Level has Paper 1 Theory Fundamentals (1 hour 30 minutes) and Paper 2 Fundamental Problem-solving and Programming Skills (2 hours), both written. The full A Level adds Paper 3 Advanced Theory (1 hour 30 minutes, written) and Paper 4 Practical (2 hours 30 minutes), a programming test taken on a computer in Python, Java or Visual Basic. Pseudocode follows the Cambridge pseudocode guide. Each module below uses the syllabus topic names.

Learn with an affordable 1:1 mentor who explains each topic, practises past-paper style questions with you and helps you write clear pseudocode. Message us on WhatsApp or email, or fill in the short form, for a free, no-obligation chat. We will suggest a plan that fits your budget and flexible timings in your time zone, and you can start this week.

FAQs

Cambridge A Level Computer Science 9618: frequently asked questions

Is there a self-study option?

Not for this syllabus directly. We have free Python practice problems that help with programming, but this course is taught through 1:1 mentoring.

How much does mentoring cost?

1:1 mentoring is personal online tutoring and is affordable, with plans that fit your budget. Tell us your goal and how often you would like sessions, and our team will suggest an option that works for you in a free, no-obligation chat.

How do I get started?

Message us on WhatsApp or email, or fill in the short form on this page. Our team replies, talks through your papers, your teacher's pace and your exam dates, and arranges a mentor at flexible timings in your time zone. You can start this week.

Do you cover both AS and A Level?

Yes. AS Level covers Papers 1 and 2 (topics 1 to 12), and the full A Level adds Papers 3 and 4 (topics 13 to 20).

Which language is used in Paper 4?

Paper 4 is a practical programming test on a computer, and candidates can use Python, Java or Visual Basic. Your mentor teaches in the language your school uses.

How do I learn Cambridge pseudocode?

Your mentor teaches the layout and keywords from the official Cambridge pseudocode guide, then you practise writing and tracing algorithms in pseudocode until it feels natural.

Will a mentor complete graded work for me?

No. Mentors teach and explain ideas and help you practise. They never complete graded work, tests or assignments for a student.

Is it 1:1, and how will we know my student is improving?

Yes, every session is one mentor and one student, online. The mentor sets clear goals for each block of sessions and reviews them together, and practice on MentorNxt shows in the learner dashboard.
