Is this course right for 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.

Students from around Chennai
A student anywhere in Chennai can take IGCSE Grade 9 Computer Science (CS) 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.
How Chennai students attend
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, exactly as they would in a classroom. 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.

My Twin daughter attended 15 day Class 12 Computers online revision crash course right before the Board Exams. The sessions were very organized with all topics and chapters covered comprehensively. They had access to chapter wise notes and previous years question papers and sample papers after login which were very helpful. Kajal Ma'am teaching was excellent and my kids were very happy with the benefit they received. The backend was seamless and I was very impressed by the professionalism and proactive methods utilized to give the best for the students. I recommend Kwickprep and Kajal Ma'am unreservedly.
