Students say
Don’t take ZAK’s word for it.
Real students, real schools, real results — every testimonial is submitted with credentials and approved by ZAK before it appears.
I had the privilege of being taught Computer Science by Sir Zafar Ali Khan during my O and A Levels, and I will always be deeply grateful that I was his student. He is an exceptional teacher, but what I value most is the genuine care, generosity and selflessness he has always shown me. He gave me his time, knowledge and support so freely, often going far beyond what anyone could expect from a teacher. Much of the confidence and passion for learning that I carried forward in life began in his classroom, and I truly believe his influence played a part in the person I became. Even years later, he has never hesitated to guide or help me whenever I have reached out. Some teachers leave you with good grades Sir Zafar left me with something far more lasting. I can never fully thank him for everything he has done for me, and I feel incredibly fortunate to still call him my mentor.
ZAK didn’t just teach Computer Science; he had an incredible way of inspiring and uplifting his students. From supporting us in the classroom to being there for us and responding even after class hours, ZAK always went above and beyond. The love for CS that I developed started with his classes, and I’m genuinely grateful for that foundation. With technology evolving so rapidly, I can only imagine how much more enriching the experience of learning from him must be today
I was fortunate to study A-level Computer Science with this teacher in Pakistan. He made the classroom welcoming, explained difficult concepts clearly, and always made learning enjoyable. His teaching has stayed with me well beyond A-levels. The foundation he gave me in computer science, especially low-level languages, has been incredibly helpful as I study at Simon Fraser University in Canada. Many of the concepts we covered and assignments we completed prepared me for my first- and second-year university courses. He is a friendly, dedicated, and truly excellent teacher. I’m grateful for the confidence and strong foundation he helped me build.
