What is the best way to use busuu to have the best experience?

In the process of learning English, I encountered various difficulties in the sense that many words and phrases that seem neutral to me can actually be even passive-aggressive. I advise you to study articles like this one https://promova.com/blog/passive-aggressive-phrases-in-english to distinguish between these phrases and not to use them where it is inappropriate.

You can use on your mobile or your laptop, but I would suggest to start a study plan so Busuu will create automatically the best experience for you based on your goals.
