Hi there,

Good question! I am studying 4 different languages and definitely understand the struggle. Here are my 3 top tips:

1. Find a teacher. I am personally using preply.com, another alternative is italki.com. You can filter teachers based on languages, reviews, budget, availability, etc, similarly to PrepLounge coaches. I am using it for a couple of languages and it works really well. In your case, you should target teachers willing to help you with business terms. Working with a teacher is relatively cheap and helps enormously if you manage to stick to a weekly class
2. Study daily new words. I recommend the app Anki, which uses the SRS system – the best way to learn new words. Focus on the words critical for your job – usually, if you master the 1000 most important ones, you can talk and understand relatively well your niche
3. Gamify your learning. I tried a few apps and the one I liked the most in terms of gamification is Memrise (focused mainly on building vocabulary) – you should target a course based on business terms in your case (you can add for free one of those created by the other users, besides the official ones offered by the app)

BONUS: find a good business book on Audible, check if you like the style of the speaker (it is very important) and listen to it in down time. You will both learn new things and improve your English.

Best,

Francesco
