Testimonials


I had since long aspired topping Nepal in at least one subject. I was well aware of my potentiality, but I needed to be more shrewd and perhaps I needed more exposure. I had to know other folks and what they were up to. Computing 9691 page gave me that particular opportunity and today I have flying marks in Computing, plus a chance to top Nepal.

And lastly, thank you Sir, not just for your precious support, which I would fail to explain in mere words, I shall be indebted to you forever.

Computing 9691 is probably the best site around for the subject. The detailed resources along with the friendly navigation system makes the site very easy to use. Need past papers? on the site, need presentations? on the site, need notes? on the site. There's a reason why this comes up on Google search before the CIE's website.
Thank you Sir for your dedication and hard work.

Its one the the best sites to refer to if you are a Computing student. Relevant and up to date material plus 24/7 support by Sir Zafar makes it even better. Thank you Sir for everything you have done for me and for others as well. Inshallah will try to to be of any sort of help you need in your efforts to make Computing 9691 even better.

This is one of the best sites I ever browsed for the course material. Every thing updated and well explained. About the teacher, Mr Zafar is one of my inspirations in the field of computer science. The support and he provides with the help of this website is commendable, the website is also utilised by people who cannot afford to join a school, I have also recommended this site to some local friends who are not enrolled in CIE examinations and they also find it useful.

Great Work Sir, I wish this initiative will keep working for the benefit of the students and the improvement of the subject.
