Every named Cambridge Computer Science topper we've taught since 2018 — school or private candidate, level, distinction, and in their own words. Nothing here is a promise. It's a record you can check.
"Sir Zain made sure his students had all the bases covered. He would go beyond what was expected to help out his students and would take out time to help us individually outside of class. The classes were never boring and Sir Zain made good use of tools and software available online to really help us understand concepts."
"Sir Zain is an extremely passionate teacher who makes learning computer science engaging for everyone. His teaching strategies for A Level Computer Science are highly effective, and his approach ensures that students master each specification of the course. He also sharpened our problem-solving skills by giving us fun open-ended tasks. Even today, I regularly apply the innovative problem-solving techniques that he taught us in my professional life."
"Sir Zain is an exceptional teacher who constantly motivates his students to do better. He regularly checks our concepts and makes sure we show improvement. As a private candidate, I often doubted myself but he always motivated and guided me. Most importantly he puts in his own effort and his notes/topical past papers were extremely helpful. His help, guidance and motivation helped me achieve not just an A* but also a DISTINCTION!!"
"'CS teacher' is too narrow a title to describe what Sir Zain does on a daily basis in his classes. He still teaches the required CS syllabus, and does that damn well, and this award is partially proof of that. But what makes him stand out is the support he provides his students outside the classroom. If you're thinking about choosing him for CS, I don't think there's too much to think about, to be honest."
"Before my classes with Sir Zain, my concepts and ideas were vague. The online classes made the learning process far easier — his well-written notes and constant support cleared many of my notions and further assisted me with my preparations. He directed me whenever I was baffled. If it wasn't for him then I wouldn't have been able to achieve this award. His efforts truly paid off."
"I've been studying Computer Science with Sir Zain for the past two years, and this year I got the highest marks in Computer Science in Sindh and Balochistan. The lecture notes, the lectures, and the way he explains things often make very complex concepts really simple to understand. Outside the classroom he's very approachable — one of the best sources of guidance when it comes to making the right choices for your future. I trusted him with my own A Levels, and so should you."
The August 2026 cohort is enrolling now — O Level, IGCSE and A Level Computer Science, in Karachi and online.
