From first programs to complex algorithms, our specialist tutors build the logic step by step, then show how examiners want it written.
Computer science mixes programming, maths-style logic and a lot of theory, and gaps from the early years show up at GCSE.

Specialist tutors, clear progress tracking, and curriculum-specific expertise tailored to your child's goals.
Every tutor holds a degree from a top university and passes our vetting process.
Tutors who know AQA, Edexcel, OCR, Cambridge and IB specifications and mark schemes.
Sessions fit around school timetables and any time zone, with easy rescheduling.
Real stories from families who saw grades rise and confidence return.
“My daughter was struggling with IB Mathematics HL and had almost given up hope of getting a 7. After just two months of weekly sessions with her Roots tutor, her confidence soared and she went from a predicted 4 to a final grade of 6. The personalised approach made all the difference—her tutor identified exactly where the gaps were and worked through them systematically.”
Sarah M.
Parent of IB Student
“I started tutoring for A-Level Physics about three months before my exams. My tutor was incredibly patient and broke down complex topics like electromagnetic induction into simple, intuitive steps. I ended up getting an A* which I genuinely didn't think was possible. I'd recommend Roots to anyone who wants a tutor that actually cares about your progress.”
James T.
A-Level Student
“We needed help with GCSE Science for my son who found chemistry particularly challenging. His tutor made the sessions engaging and relatable—using real-world examples that finally made reactions and bonding click for him. He improved by two grades and, more importantly, actually enjoys science now.”
Priya K.
Parent of GCSE Student

Computer science asks students to do two quite different things well. Programming needs logical thinking, careful tracing and lots of practice; theory needs exact definitions about hardware, networks, data representation and security. Students who enjoy coding can neglect the theory, and students who memorise theory can freeze when asked to write an algorithm by hand. Gaps also build on each other: a student who never quite understood loops or arrays will find data structures and searching algorithms much harder later on.
JCQ's 2026 results show only 29.9% of GCSE Computer Science grades across the UK reached 7 or above, while 70.6% reached grade 4. DfE data for England shows that 23.9% of Year 7–9 computer science teaching hours in 2025/26 were taught by teachers without a relevant post-A level qualification. In the US, 23% of AP Computer Science A students scored the lowest possible 1 in 2026. The encouraging news is that the Education Endowment Foundation finds one-to-one tuition adds around five months' progress on average.
A good tutor finds the exact concept where your child's understanding breaks down, whether that is loops, functions, recursion or binary, and rebuilds from there. Sessions mix live coding on a shared screen with written practice: tracing algorithms, writing pseudocode and answering theory questions in the precise language mark schemes reward. Tutors also help students plan and test larger programs and prepare for any onscreen programming exam. Tuition works best when it follows the classroom, so we use your child's own specification and language.
We tutor GCSE Computer Science (AQA, OCR and Edexcel), Cambridge IGCSE Computer Science (0478), A-Level Computer Science, IB Computer Science at SL and HL, including the new course first assessed in May 2027, and AP Computer Science A and Principles. Cambridge's 0478 syllabus currently accepts pseudocode, Python, Visual Basic or Java, and from 2029 it will use Python 3 only. Families join us from the UK, UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, Oman, Canada and the US, with sessions online and scheduled around your time zone.
