"Understanding over Memorization"
Expert tuition for Cambridge CIE (0478) and Edexcel (4CP0) IGCSE Computer Science. Step-by-step explanations. Real understanding. Exam-ready confidence.
Too many students memorize code without understanding how it works. At TristanNyan CS Tuition, every concept is broken down logically — step by step — so you can solve any problem, not just the ones you've seen before.
Every concept is explained through logic and reasoning. No rote memorization of code patterns — you'll understand the why behind every line.
Past paper walkthroughs, mark scheme analysis, and structured answer techniques. You'll know exactly what examiners want to see.
Every session comes with structured notes and recordings so you can review material anytime, at your own pace.
A teaching style that feels like learning from an experienced friend — approachable, patient, and always ready to re-explain until it clicks.

Real messages from real students. Their results speak louder than anything we could say.
"Thank you sayyar, I got A in computer science because of you."
"Your teaching style is really good, I can understand well. Before we started, I struggled with pseudocode and exam questions. Your step-by-step explanations helped the most."
"I've had an amazing experience with Sir Tristan! Before joining, I struggled a lot with pseudocode. The teaching style is clear, and engaging. Highly recommend to anyone looking to boost their performance and actually enjoy learning!"
"My CS grades before joining were around C and barely a B average. After taking your classes with your logical explanation on programs, I could do Paper 2 without any issues. You are an amazing teacher, with your approach of all logic and no memorization."
"I got 96/100 for CS, it surprises me a lot! I got 66/100 in my previous exam which was really horrible — it was before I met you saya. I was memorizing the loops back then!"
"I've become more confident in writing programs on my own which I couldn't do well before. Your teaching style is patient and clear, and it really encourages me to think through problems."
"Since we began, I've noticed a big improvement in my understanding and confidence in Computer Science. I now feel much more comfortable writing pseudocode and understanding how algorithms work."
"The biggest challenge before I joined was that I didn't really know how to apply concepts in real situations. Your explanations are super clear and gave me the confidence to start writing my own code."
"I enjoy the examples you use which are easy to understand and quite to the chase. I like the friendly style where it's not just a teacher but more of someone who's more experienced in the field teaching me."
