About your teacher ```

I don't just teach Computer Science. I teach students how to think.

I'm Afrasiab, a Cambridge O & A Level Computer Science instructor based in Lahore. Over the years, I've worked with students who understand the theory but struggle when the question changes, the code doesn't behave as expected, or the mark scheme demands something more precise.

That's where Siab Syntax comes in. My approach is simple: understand the concept, break it down, practise it, and debug the mistakes. Whether it's algorithms, programming, data structures, computer architecture, or exam technique, I focus on making difficult concepts feel logical rather than overwhelming.
