I'm Mahamuda Akther, Assistant Teacher, DIS Chandpur. I designed this course for the student of STD VII. This is a era of communication and globalization. For that English is one of the most powerful tools for pursuing studies, inter-cultural communication and job markets at home and abroad. A student who communicates more information with a few mistakes is more likely to communicate successfully than one who conveys very little with no mistakes. The approach is designed to motivate students to communicate.
