Why this fits a Ahmedabad student

Schools in Ahmedabad sit across Gujarat Board (GSEB), CBSE and ICSE. GSEB is a board we teach directly, so a Ahmedabad student on the Gujarat Board is taught their own paper pattern.

Students across Ahmedabad

A student anywhere in Ahmedabad can take CBSE Class 12 Computer Science (CS) with us — Because, Bodakdev, Bopal or Centre included — because the class is online and there is no centre to travel to. Ahmedabad sits in Gujarat, where the Gujarat Board (GSEB) 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 Ahmedabad asks questions in the moment. Recordings are provided for revision only.

Shubhranshu enjoyed the classes with Kajal Mam as she taught really well. She kept him engaged even in online classes. He joined the classes just few months before exams and still managed to score well as Kajal Mam taught him strategically and continuously. Hats off to her hard work and perseverance.
