21K School Timetable, Class Timings and Learning Rhythm
Live class hours vary by grade, pathway and cohort, with independent learning, activities and breaks forming part of each learner’s day.
Online school should create a reliable learning rhythm without asking a child to spend the entire conventional school day on screen. 21K School schedules live classes by stage, pathway and cohort, with independent work, activities and breaks completing the learning experience. Our next cohorts start in September 2026, January 2027 and June 2027, so families can choose the cohort that suits the academic calendar of their region.

As a parent, one of the biggest advantages of 21K School has been the flexibility it offers without compromising on academic support. My son, Aarav Sanjay, is currently in Grade 10 and has been a student here for the past two years. As a competitive tennis player participating in national-level tournaments, a conventional schooling structure would have made it extremely difficult for him to pursue his sporting ambitions seriously.
