Why this fits a Pattukkottai student

Most Pattukkottai schools follow the Tamil Nadu State Board (TN SB), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the TN SB computer paper itself, so this course suits a Pattukkottai student in one of those schools.

✓Live classes at Indian Standard Time, never pre-recorded
✓Small batch or one-to-one, so a Pattukkottai student can interrupt and ask
✓Taught by Kajal Ma'am, teaching computer subjects since 2006
✓Free demo class before any payment

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.
