CBSE Class 12 Computer Science (CS) Classes in Kochi, Online Coaching

Why this fits a Kochi student

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

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

Students across Kochi

A student anywhere in Kochi can take CBSE Class 12 Computer Science (CS) with us — Bhavans, Chinmaya, DHSE or Edappally included — because the class is online and there is no centre to travel to. Kochi sits in Kerala, where the Kerala Board (SCERT) 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 Kochi 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.
