Take control of your business English classes.
Many teachers enjoy talking about subjects they like but that business English students don’t find useful. Don’t fall into that trap.
Take control of your business English classes. List all the situations you need English for, and work out the phrases you find useful. Afterwards, role play those situations with your teacher until they become automatic. It’s the only way to effectively learn business English.
