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

Students from around Kolkata
A student anywhere in Kolkata can take CBSE Class 11 Computer Science Essentials (CS) with us — Ballygunge, Bengal, Lake or Martiniere included — because the class is online and there is no centre to travel to. Kolkata sits in West Bengal, where the West Bengal Board (WBBSE/WBCHSE) runs alongside the national boards, so we are asked about both.
How Kolkata 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 Kolkata asks questions in the moment, exactly as they would in a classroom. Recordings are provided for revision only.
