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 IGCSE Grade 9 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 have joined kwick revision course before board examination. It found very useful for preparation of board examination. Educator cover all the topics. Investment of time was worth. Study material and sample paper practice were well organised.

★★★★★
I had a very good experience with Kwickprep. The course was excellent in every way, the teaching, the study materials, and the support from the educators were all top-notch. What helped me the most was the consistent practice in Computer Science, which made it easier to revise and stay confident during the final days before the exam. The staff was kind and always ready to help, and the way they explained both the concepts and exam-writing techniques really made a difference. Overall, it was completely worth it, and I'm really thankful for the support and guidance I received throughout the course.
