Is this course right for a Visakhapatnam student?
Most Visakhapatnam schools follow the Andhra Pradesh Board (BSEAP/BIEAP), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the BSEAP/BIEAP computer paper itself, so this course suits a Visakhapatnam student in one of those schools.
