Is this course right for a Ranchi student?
Most Ranchi schools follow the Jharkhand Board (JAC), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the JAC computer paper itself, so this course suits a Ranchi student in one of those schools.

Students from around Ranchi
A student anywhere in Ranchi can take CBSE Class 11 Computer Science (CS) with us — Academic, Birla, Convent or Council included — because the class is online and there is no centre to travel to. Ranchi sits in Jharkhand, where the Jharkhand Board (JAC) runs alongside the national boards, so we are asked about both.
How Ranchi 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 Ranchi asks questions in the moment, exactly as they would in a classroom. Recordings are provided for revision only.

I'm deeply impressed by the supportive environment fostered by Kajal Ma'am during the Kwickrevision workshop. Her approach not only facilitates a thorough understanding of the subject matter but also encourages a collaborative and nurturing learning experience. This workshop stands out as one of the best I've ever attended, and I attribute much of that to Kajal Ma'am's exceptional guidance.
