GCSE and A Level Computer Science tuition online from University of Edinburgh Software Engineering student who recently achieved A* in AQA Computer Science

Colm taught CS to my daughter Sadhbh for GCSEs. He is really so knowledgeable, not only of the spec but also past papers and the mark schemes showing her exactly how she could get maximum marks for her questions. He made lessons fun and engaging and she even said she felt confident and prepared for her exam.

Having recently completed my A levels alongside Colm and achieving an A* in maths, I can confidently say that his help played a huge part in my result. I thought that getting tutored by my friend would mean that we get no work done, but that couldn’t be further from the truth. I think by far the most helpful part was how recently he had completed the course and his precise explanations of what each part would make me think. He knew the exact problems I was facing and the problem with my thought process because he had faced the same issues months before me while learning. He was very clear and made sure I understood any problem before moving on. I cannot thank him enough.

My daughter (Y8) was completely in the dark about Python code, but with Colm’s consistent and effective tutoring she was able to obtain a top grade in her final exam. He explained all the concepts clearly and my daughter is very confident thanks to his help! We are looking forward to further sessions with Colm in the future!

Colm tutored me in both Maths and Computer Science throughout my GCSEs, and I couldn't recommend him enough. When I started with him halfway through Year 10, I was predicted a 7 in maths, but with his support I achieved a comfortable grade 9, and gave me the confidence to take on A-level maths. He made difficult concepts easy to understand, helped me stay on top of schoolwork, practically taught me how to code in python from scratch and always made sure I was focused on the areas I needed to improve on. The best thing I can say about Colm was how fun he made learning, he taught maths and CS in a way that made me enjoy the subjects more than I ever have and I genuinely looked forward to our sessions. I'm extremely grateful for all his help and would highly recommend him to anyone looking for a tutor.

I was in the year below Colm at Dubai College, and completed my GCSE examinations in June 2025. Initially I struggled with Physics, but after tutoring with Colm my grade increased from a 5 to an 8. He is a very patient and clear teacher, and I am truly grateful for his help.
