Students across Chandigarh

A student anywhere in Chandigarh can take IGCSE Grade 9 Computer Science (CS) with us — Does, Fields, Mohali or Panchkula included — because the class is online and there is no centre to travel to. Chandigarh sits in Chandigarh, where the CBSE-affiliated schools (CBSE) 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 Chandigarh asks questions in the moment. Recordings are provided for revision only.

My experience with Kwickprep was good. They guided me well for the Boards. That's why I would recommend Computer Science Aspirants to join Kwickprep, as their teaching and study material is the best among all others. Kwickprep is the best choice for classes 11 and 12.

My experience with Kwickprep was really good. The course quality, teaching style, and study materials were excellent, and everything was explained in a clear and simple way. What I found most helpful was the last-minute theory material, it was extremely useful for quick revision and helped me cover the entire year's basic syllabus efficiently. The suggestions and lectures during that time were very informative and played a big role in boosting my preparation. I'm quite satisfied with the course overall, and it definitely helped me improve my results.
