My Teaching Approach

Courses I Teach

G9 / G10 Computer Science (NEB Curriculum)
G11 / G12 Computer Science & Information Technology
+2 C Programming, Database, Web Development
Extra Data Analysis & Excel for Beginners

Teaching Philosophy

I believe every student can master technology — the key is meeting them where they are. I break complex topics into digestible steps, use real-world analogies, and always connect theory to practice.

My classroom is a safe space for questions. No concept is too basic to ask about. Progress is celebrated, not rushed.

Focus: Practical Learning

Theory without practice is incomplete. Every lesson I teach has a corresponding hands-on activity — whether it's writing your first SQL query, building a webpage, or analyzing a dataset. Students graduate from my class with a portfolio, not just notes.
