IGCSE Grade 9 Computer Science (CS) Classes in Jaipur

Is this course right for a Jaipur student?

Most Jaipur schools follow the Rajasthan Board (RBSE), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the RBSE computer paper itself, so this course suits a Jaipur student in one of those schools.

Students from around Jaipur

A student anywhere in Jaipur can take IGCSE Grade 9 Computer Science (CS) with us — City, Founded, Jagatpura or Malviya included — because the class is online and there is no centre to travel to. Jaipur sits in Rajasthan, where the Rajasthan Board (RBSE) runs alongside the national boards, so we are asked about both.

How Jaipur 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 Jaipur asks questions in the moment, exactly as they would in a classroom. Recordings are provided for revision only.
