It was lovely to meet you, Rafał! I would say you probably have a borderline B1/B2 level of spoken English. You used lots of good expressions today (like "first things first" and "no matter which language") and your grammar was generally on point too :) Just watch out for your auxiliary verbs in different tenses: I go, I don't go I went, I didn't go BUT I'm going, I'm not going I was going, I wasn't going Another little thing I forgot to mention was when you said "They start to working". You can actually use both the infinitive and the gerund (-ing form) with 'to start', just not together. So you can say either 'They started to work' or 'they started working'. All you need to do now is polish off a couple of those little mistakes and keep working on your general fluency. I'm sure you'll be able to get to an advanced level in no time! :)
