Why this fits 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 across Kolkata

A student anywhere in Kolkata can take ICSE Class 9 Computer Applications 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.

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. Recordings are provided for revision only.

What students & parents say

4.9/5 from 36 verified reviews.

★★★★★

I was also preparing for my JEE entrance exam. I thought that I was not able to complete the syllabus in a short period of time, but as per the commitment, the course has been completed, and I got a thorough revision too, which was quite useful. The Kwickprep course, study material, and quality of teaching were good. I got support during my practical examination. Doubt solving took place in very less time. I am satisfied with the course.

Learning with kwickprep has been a wonderful experience. It has a very user friendly interface and is aesthetically pleasing. It provides all the important points and the proper explanation of the topics without prevaricating from the original topic.
