I am an experienced and dedicated Computer Science educator with over 10 years of successful teaching across the ICSE, ISC, CBSE, IGCSE, IB, and AP Computer Science A (CSA) curricula. Holding a Master’s degree in Computer Applications (MCA), I possess strong command over both theoretical concepts and practical programming skills. I have mentored and groomed over a hundred students, guiding them confidently through school assessments and external board examinations. Majority of my AP students consistently score 4 or 5 in the AP CSA exam, and the IGCSE and IBDP students achieve top grades (A/A* or 7 points) in IGCSE and IBDP Computer Science exams. Almost 100% of my ICSE and ISC students score over 95%, many scoring the perfect 100.

I offer both offline (at my home) and online classes, blending flexibility with a structured and disciplined learning environment. My teaching approach includes specialized notes, thoughtfully designed assignments, and scientifically planned training techniques that help students build strong conceptual understanding, develop problem-solving skills, and gain complete exam readiness.

What sets my training apart is its progressive, staircase-like structure — where each student steadily rises to the top level through continuous, guided advancement. Uniquely, pseudocode exercises are also executed on machines to verify results, making the learning both practical and completely satisfactory.

Here are the key highlights of my training approach:

✅ Over 100 students successfully trained
✅ Majority score A/A* or 7 points in IGCSE/IBDP
✅ Almost every ICSE/ISC/CBSE student scores over 95% with many scoring a perfect 100!
✅ In AP CSA Examination, most of my students score 4 or 5 points
✅ I provide students with carefully-designed specialized notes, structured daily assignments & concept-based training
✅ Affordable fee structure
✅ One-on-one classes offered for personalized attention
✅ Free demo class to experience the teaching before enrollment
✅ For IGCSE and IB students, pseudocodes are always executed on machine for hands-on understanding
