CBSE Class 12 Computer Science (CS) Classes in Kannur, Online Coaching

Why this fits a Kannur student

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

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