William Harmer

GCSE and A-level Computer Science tutor for students of all abilities.

In-person lessons available around Cambridge (contact for price). Online lessons available anywhere (£30/hr).

I'm super friendly and approachable, with teaching tailored to each student’s ability, goals, and preferred learning style.

I graduated in July 2025 from the University of East Anglia with a First-Class BSc (Hons) in Computer Science.

Familiar with all major UK exam boards: AQA, OCR, Edexcel, etc.

What to expect from lessons:
For students having regular lessons, lessons can cover the entire syllabus from start to finish, follow the same pace as their lessons at school, or be structured around whatever approach they find easiest to learn. I will always work at a pace that suits the student's abilities, whether that means taking more time to fully understand a topic or moving quickly through areas they are already confident with. As every student learns differently, lessons can vary from person to person and are tailored to their individual needs.

About me:
After graduating from university, I began tutoring several students who needed additional support with Computer Science. Through this experience, I discovered how rewarding it is to help others learn, which inspired me to expand my tutoring through this website. I strongly believe that every student has a unique way of learning, so I tailor my teaching to suit each individual’s needs and goals. Rather than encouraging students to simply memorise information, I aim to foster creativity and active learning by helping them understand why computers behave the way they do. This deeper understanding strengthens long-term retention and equips students to apply their knowledge confidently in exam situations.
