04 / THE PERSON BEHIND THE PROGRESS
A teacher who gets
the student side.
Computer Science should feel like something you can figure out — not something you have to memorise.
I'm Hasan Zeyn, founder of The Great Student and a Computer Science undergraduate. I've spent over eight years helping students turn difficult ideas into understanding, from school-level programming to university computing.
My teaching experience includes college classrooms and private tutoring for students across the UK, Qatar, Saudi Arabia, Oman and the UAE.

STUDENT REVIEWS
Their progress, in their words.
From Computer Science students taught by Hasan Zeyn.
“In the month before my exams, I was able to clear up all the concepts I’d been struggling with.”
“Thanks for all the help. I got a grade 6, just four marks off a 7. I might ask for a remark and see if I can pick up those last few marks.”
“We covered my IGCSE work and then started putting programming into practice. I even used automations in my streaming setup.”
“Programming feels so much easier now. I can even teach my Year 8 classmates, and we’re learning things beyond what my school covers.”
“While homeschooling for my October–November exams, I went from scoring in the lower half to 80% in two and a half months.”
