Students across Chandigarh

A student anywhere in Chandigarh can take CBSE Class 12 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.

I have enrolled in the CS40 session. It was very useful for me in a short period of time. Kajal Ma'am answered the call immediately and also solved doubts. I got enough practice before the board examination. The study materials and sample papers provided before the examination were up to the mark.

The instruction is exceptional, and I'm especially grateful for the meticulous attention to resolving even the slightest uncertainties. The Kwick Revision workshop provided extensive practice opportunities and the concepts were reiterated by ma'am for clarity, ensuring a comprehensive understanding.
