ICSE Class 9 Computer Applications Classes in Chennai, Online Coaching

Why this fits a Chennai student

Most Chennai schools follow the Tamil Nadu State Board (TN SB), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the TN SB computer paper itself, so this course suits a Chennai student in one of those schools.

✓Live classes at Indian Standard Time, never pre-recorded
✓Small batch or one-to-one, so a Chennai student can interrupt and ask
✓Taught by Kajal Ma'am, teaching computer subjects since 2006
✓Free demo class before any payment

Students across Chennai

A student anywhere in Chennai can take ICSE Class 9 Computer Applications with us — Adyar, Anna, Chinmaya or Nadar included — because the class is online and there is no centre to travel to. Chennai sits in Tamil Nadu, where the Tamil Nadu State Board (TN SB) runs alongside the national boards, so we are asked about both.

Every class is live at Indian Standard Time, in a small batch or one-to-one. Nothing is pre-recorded, so a student in Chennai asks questions in the moment. Recordings are provided for revision only.

I had a really good experience with Kwickprep. The course was well-structured, the teaching was clear and effective, and the study materials were very helpful in making the concepts easier to understand. What I found most valuable was the question practice, which helped me apply what I learned and strengthen my understanding. The support from the educator was always available when needed, and overall, I'm quite satisfied with everything I learned during the course.
