About A Level Computer Science
A Level Computer Science is the qualification students sit in their final year of school. It suits anyone heading for computer science, software engineering, data science or cyber security degrees. It runs over two years: Year 12 first, then Year 13, when the exams happen. Many schools call that second year A2, and others call it Grade 12. You can see how A Level is structured across both years.
The step up from GCSE is real, and it is not just more programming. Students have to explain how computers work: data representation, networks, databases, algorithms and the theory of computation. Answers need precise technical language. On the programming papers, a solution that runs is not enough, because marks also go to clear structure and good testing.
Every lesson starts from the specification your child's school follows, so study time goes where it counts. We mark real past papers and show exactly where the marks went, and we pull extra practice from our past paper library. Parents can follow progress in the Centaurus Academy LMS all through Year 13.
Who A Level Computer Science Is For
This course suits Year 13 students who want a computer science grade they can rely on.
- Year 13 students in the final year of A Level
- Students aiming at computer science, software engineering or cyber security degrees
- Learners pushing from a B up to an A or A*
- Students who can code but lose marks on written theory answers
- Retake students who need a better grade this summer
A Level Computer Science Exam Boards We Cover
AQA is a UK board, where the exams come at the end of the two years. Cambridge International, OxfordAQA and Edexcel International follow their own international syllabuses, with exams in more series. What they all share is programming tested under exam conditions, on screen or at a computer. We teach to your child's exact specification and language.
Edexcel
This is the International A Level route, and it is modular: four units of 80 marks, sat across exam series in January and June. Two units are written or onscreen exams. The other two are three-hour practical programming exams, where students build and refine a solution in Python 3. At least 10% of the marks are for maths.
AQA
Three components. Paper 1 is a two-and-a-half-hour on-screen exam worth 40%, where students write and adapt programs. AQA issues a skeleton program and preliminary material beforehand, so there is real preparation to do. Paper 2 is a written paper of the same length. The final 20% is a practical project.
Cambridge
Four papers of 75 marks. Papers 1 and 2 are the AS papers and cover theory and programming. Paper 3 adds advanced theory. Paper 4 is a two-and-a-half-hour practical exam sat at a computer, where Cambridge warns that work not saved into the evidence document scores nothing. Exams run in June and November.
OxfordAQA
Four units, with the International AS worth 40% of the grade and the A2 the other 60%. Programming is examined on screen in C#, Python or VB.Net. Unit 1 lasts two hours and Unit 3 lasts two and a half. The advanced theory unit covers functional programming, cyber security, databases and artificial intelligence.
How Centaurus Helps A Level Computer Science Students Excel
Programming Under Exam Conditions
Three of the boards test coding on screen or at a computer. We practise in the same setup, with a code editor and no internet, so the conditions hold no surprises.
Skeleton Program Preparation
AQA releases a skeleton program and preliminary material before Paper 1. We work through it line by line, so your child walks in already fluent in the code.
The Practical Project
AQA's project is 20% of the A Level, and it is easy to leave too late. We break the analysis, design, build, testing and evaluation stages into a plan with real deadlines.
Theory in Plain Terms
Data representation, networks, databases and the theory of computation are where marks quietly disappear. We turn each topic into plain explanations and past-paper practice.
Evidence Document Discipline
On Cambridge Paper 4 and the Edexcel International practicals, unsaved work scores nothing. We drill the save-and-record habits that protect marks.
24/7 Progress Reporting
Families get access to the Centaurus Academy LMS, with attendance, progress and lesson notes available to parents, students and teachers at any time.

What Parents Say About Us
Hear from the parents and students who have experienced our personalised teaching first-hand.
Excellent long-term experience
We have an excellent long-term experience with the academy and Sir Awais. Our three children studied with them during different periods and succeeded well. We highly recommend the academy.
Excellent academy
Centaurus Academy is truly one of the best educational institutions I've come across. The environment is nurturing, the staff are incredibly dedicated, and the quality of education is outstanding. They focus not only on academic excellence but also on character building and personal growth. The teachers are supportive and go the extra mile to ensure every student feels confident and motivated.
My child has gained confidence
I'm very satisfied with the dedication and teaching approach. My child has gained confidence and improved significantly in understanding math concepts, thanks to the teacher's clear explanations and supportive guidance.
