Learn basic & advanced English in a simple way

I am from Bangladesh. I completed my MBA in HRM from East West University, Bangladesh. I had been working in a multi-national company named GrameenPhone Ltd. That was the most & best successful telecom operator company in Bangladesh. I served that company more than 7 years. While working there i developed my English speaking, writing qualities. Because I know that people feel shame to speak English in every day life. I want to convert this disability to an opportunity. Please learn & practice. Its super cool. And also very easy to learn English
