Okay, so the next question is coming, it comes in from Robert. First off, I would like to say how much I like Glossica. My question is what do you need to do to move from the B1 to B2 level or B1B2 level to the C1 level? Most of the difference here is not necessarily grammar or syntax. That's the kind of stuff that you should have learned back in the A levels, especially with even all of the verb tenses and how the sentences are put together. The major difference between B1 and B2 and C1 is basically the professionalism with how you speak. So, with my analysis of languages from around the world, I've gone and learned quite a few aborigining languages. You'll find that the customary way of speaking, these languages are not used in professional settings. And so, there's a lack of vocabulary and there's, you know, they're not used to write, they're not used to write papers or scientific things. Even though they do have scientific words for plants and animals, most of it is botany and flora and fauna. You're not going to have these languages having the capability to express things in a more empirical or scientific way. And so, that's where you're starting to get a big difference between languages and their professionalism with how they communicate and how the rhetoric is developed. Most of that rhetoric is developed because languages have developed writing systems. And so, those writing systems allow the language to be parsed better for people to create better sentences. And so, when you go into a community where a language is spoken, but yet they've never learned how to write the language, languages, even for fluent speakers of those languages, are rarely used beyond like a B1 level. And so, the major difference between a B1 level and a B2 level is just this major expansion of vocabulary and being able to speak in a more concise way, on better rhetoric, on better choice of words. In fact, I remember with a specific average in language that I was working on, I would say that is there a way to communicate in a B2 level in that language? I think that yes, there is because there was some, when you get speakers who can tell you stories and they're able to elaborate and use a lot of complex ideas and words and throw them into that story, I feel like, wow, it's getting harder and harder to understand the story that this person is telling me. It's almost like my level is not good enough because they're using such a vast amount of vocabulary. This is like a B2 level in an average in language. But, you know, to find somebody who can actually tell the story in that way is really, really hard, so I can go around and talk to anybody around there in the village and nobody's going to talk to me like that at a B2 level in that language. It's just, they're just physically not capable of doing it. They just don't use that amount of vocabulary on a regular basis and even if they could, it would just kind of sound out of place. They would only be using that for a specific spot, which is for like telling the story and using this great amount of vocabulary. So that's kind of the big difference and when you get up into C1 levels, you're talking about expressions and the way of speaking and your delivery, all of these things go into creating that feel of a C1. As I'm talking to you right now on camera, I'm not even close to using a C1 way of delivery or speaking because if I were to switch to that, it might be a little bit off-putting for you. If I were to start using a lot of complex terms and grammatical terms and words from linguistics, I would lose my audience. And so it's not always a good idea to speak to somebody and a C1 level because you have to understand who your audience is. Now, if I'm going to go on stage in front of a bunch of experts in the field and I need to be using vocabulary that they understand where we can talk about these ideas specifically, then that's where C1 would come play out. So if you're a doctor and you're talking in front of you at a medical conference and you're not talking to patients, you're talking to other doctors. And you're not using the proper medical words than people will think there's something wrong with your background and training in the medical field. You know, if you're a lawyer, the same thing. If you're not citing the legal code in the right way, you're not speaking the right way, people are going to say, you don't sound like a lawyer. You should be speaking at the C1 and C2 levels for those specific professions. And so that's where the major difference is. Do does the average language learn need a C1 capacity in that language? I don't think that that is actually necessary. It just depends on what field you're going into. So if you're a scientist in a specific field and you're going to Germany to work, maybe that C1 in German is going to be really important for you so that you know all that vocabulary and you're able to function with that level.
