If your English language ability is sufficient for most simple communications, such as shopping, you may consider progressing towards BEC. You should have an understanding of, or interest in, the world of work, business and commerce.
More than ever, a good knowledge of English is needed to succeed in international business and commerce. If you can show you have relevant language skills, you'll have a great advantage in the jobs market and much greater flexibility if you want to work abroad.
BEC can help you show that you have learned English to an appropriate standard and can use it in a business context.
