A-Level Computer Science Tutor & Online Tuition
Short answer
The A-Level Computer Science course is one-to-one tutoring, taught live online: every lesson is 90 minutes.
A private group is for 3 or more friends who sign up together (the group programme is 30 hours per subject); there are no published start dates, and we agree the start date and lesson times with you.
In one-to-one tutoring, packages are from €85 a lesson.
A-Level Computer Science tutoring for OCR H446, AQA 7517 and Cambridge 9618: computer systems, algorithms and programming, and the programming project.
One-to-one and small groups · Live online · AQA, OCR and Cambridge International specifications

About the subject
A-Level Computer Science: what it covers and who it suits
A-Level Computer Science tutoring at TestPrep Europe works to the student's specification: OCR H446, AQA 7517 or Cambridge International 9618. On OCR H446 that means two written papers, Computer systems and Algorithms and programming (40% each), plus the programming project (non-exam assessment, 20%). Cambridge International 9618 has no NEA; programming is assessed in the Paper 4 Practical exam, taken on a computer.
- OCR, AQA and Cambridge International specifications mapped explicitly
- Pseudocode and language-specific code (Python / Java / VB / C#) practised side by side
- Algorithms and data structures drilled with code traces

A-Level Computer Science is strong preparation for university study in software engineering, AI, data science and cybersecurity. OCR H446 combines programming with the theory of computing: algorithms, data structures, Boolean algebra, computational thinking, processor architecture and networks.
A-Level Computer Science combines computing theory with practical programming. On OCR H446 students cover processor operation, network security, algorithm design and object-oriented software development. The programming project (non-exam assessment, 20% of the A-Level) requires students to analyse a real problem, design a software solution, develop and test it iteratively and evaluate it: a scaled-down version of a university software engineering project. Our programme builds programming fluency in the student's chosen language while drilling exam-format strategy and supporting the project.
One-to-one A-Level Computer Science tutoring
Our one-to-one A-Level tutoring is built around your current grade, your target grade and the exam board you are sitting. Each lesson works on your weak topics, drills AQA, OCR, CIE past-paper questions and walks through mark schemes, so you know exactly how marks are awarded.
A private group for A-Level Computer Science
There is no open group timetable for this subject. If 3 or more of you sign up together, we open a private group course for you. The price per student depends on how many subjects you take, with 30 hours of live lessons in each: 1 subject (30 hours) €1,031, 2 subjects (60 hours) €1,927, 3 subjects (90 hours) €2,689 and 4 subjects (120 hours) €3,496. Each student buys their own place online, and we let you know as soon as your group is ready.

How lessons work
Pseudocode + language in parallel
Pseudocode is the exam dialect; the chosen language (Python, Java, VB, C#) is the lab tool. We drill both so students don't confuse them.
Trace tables as habit
Trace tables turn iteration and recursion questions into careful step-by-step work. We make them automatic for any question that asks students to follow an algorithm.
NEA as engineering project
NEA is structured as a real software project — requirements, design, iterative build, real testing, evaluation. Final written work remains the student's own work.
Advice
A-Level Computer Science: common mistakes and study tips
MistakePseudocode that drifts into language-specific syntax.
FixOCR sets questions in its own pseudocode but accepts any clear style in answers; Cambridge 9618 expects answers in pseudocode following its own guide. Either way, a competent programmer must be able to follow the meaning.
MistakeAlgorithm answers without trace tables.
FixTrace tables make every step of a loop or recursion visible; build one whenever a question asks you to follow an algorithm.
MistakeBig-O analysis stated without justification.
FixAlways explain why an algorithm is O(n), O(n log n) or O(n²), not just state it.
MistakeNetworks answers conflating protocols at different layers.
FixTCP, IP, HTTP each have specific roles at specific layers. Layer confusion is a predictable mark loss.
MistakeNEA delivered without robust testing.
FixOn OCR, testing earns 15 of the 70 project marks (10 for testing to inform development, 5 for testing to inform evaluation) and is expected at every stage, so it cannot be added at the end without rework. Final written work remains the student's own work.
Study tips
- Start the programming project (NEA) early and meet your teacher regularly; OCR expects a well-defined problem for a real user and a non-trivial, substantial coded solution.
- Code the specification's standard algorithms yourself in your chosen language (for example Python, Java or C#): bubble, insertion, merge and quick sort, binary search, Dijkstra's shortest path algorithm and the A* algorithm, plus stack, queue, linked-list and tree operations.
- Drill binary and hexadecimal conversion, two's complement and floating point by hand under time pressure: calculators are not allowed in either OCR written paper.
- Practise writing pseudocode by hand. OCR sets questions in its own pseudocode but accepts any clear style in answers, as long as a competent programmer could follow it.
