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

Students from around Patna
A student anywhere in Patna can take IGCSE Grade 9 Computer Science (CS) with us — BSEB, Bailey, Bihar or Boring included — because the class is online and there is no centre to travel to. Patna sits in Bihar, where the Bihar Board (BSEB) runs alongside the national boards, so we are asked about both.
How Patna 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 Patna asks questions in the moment, exactly as they would in a classroom. Recordings are provided for revision only.

Learning with Kwickprep has truly been a wonderful experience. The course was well-structured, and the teaching methods were clear, effective, and easy to follow. The study materials, especially the notes and tricks shared, played a huge role in helping me prepare efficiently and score well, even in a short amount of time. What I appreciated the most was the constant guidance and support from the teacher. The way everything was taught made concepts easy to grasp and apply in exams. I'm genuinely grateful for the time, effort, and dedication put into each session. It was completely worth it. Thank you so much for everything, your teaching really made a difference in my learning journey! 😊
