In Computer Science, missing one key concept can make everything that follows harder — especially with programming, algorithms and problem-solving. I identify those gaps and rebuild your understanding step-by-step so you learn why not just the how.
You’re putting the hours into Computer Science, but rereading notes, copying code or watching random videos isn’t improving your grades. I give you a clear revision system so you know exactly what to work on, how to practise it and where you’re losing marks.
Code can make perfect sense when your teacher explains it, but when you’re faced with a blank screen, you don’t know where to start. I help you develop the problem-solving and coding skills to build solutions independently rather than relying on examples or AI to do it for you.
I'm a Computer Science undergraduate at King's College London, and I love helping students build confidence in programming, computational thinking and problem-solving.
My lessons are personalised and engaging, breaking complex ideas down so students can apply them independently — with over 3 years of tutoring experience focused on understanding, confidence and long-term academic success.
Turn difficult coding questions into simple, logical steps, so you can write code independently, no matter the complexity.
Learn to use the right tools and prompts to become a stronger programmer, enhancing your skills, not replacing them.
A roadmap personalised to exactly where you are now and where you want to be.
"He started Year 11 with a failing grade and very little confidence in the subject. Through the tutor's expertise, patience, and encouragement, he made extraordinary progress in just a few months and went on to achieve Grade 8s in his exams."
"I've been tutored by Usman for Computer Science and he has helped me massively. He's really nice, very efficient, and explains things in a way that actually makes sense. It has made a huge difference to my confidence and understanding of the subject."
"My son's knowledge and understanding of key Computer Science topics came on leaps and bounds. Usman was attentive, made complex topics more relatable, and gave constructive, targeted feedback that helped considerably with his A-Level exam preparation."
"I got my results back for my mock and I got 56/80 on paper 1 and 62/80 on paper 2. I just wanted to say thank you cs I've NVR gotten that high before and that genuinely wouldn't have happened without you and ur help."
"Usman and team helped my daughter prepare for her computer GCSEs. Within a few months, she became more knowledgeable and confident in answering the questions. The lessons definitely made a huge difference."

"Such a lovely tutor, I 100% recommend for anyone who is trying to jump the grades and willing to put in the work. Helped me jump from a grade 3 to averaging grade 7s and 8s in less than a year."
Real outcomes from the families and students behind the grade jumps.
"Usman gave my son a real handle on the core Computer Science topics ahead of his A-Levels — his understanding and his confidence in the subject both grew noticeably. Usman was attentive and had a knack for making complicated ideas feel manageable, and the feedback was always specific and useful."
