IGCSE Grade 10 Computer Science (CS) Classes in Dehradun

Is this course right for a Dehradun student?

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

Students from around Dehradun

A student anywhere in Dehradun can take IGCSE Grade 10 Computer Science (CS) with us — Academy, Clement, Dalanwala or Doon included — because the class is online and there is no centre to travel to. Dehradun sits in Uttarakhand, where the Uttarakhand Board (UBSE) runs alongside the national boards, so we are asked about both.

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