Nowadays, knowledge of foreign languages is one of the basic necessary skills and we have a lot of opportunities to learn and improve it. For instance, we can do this on our own, especially given the vast array of educational resources, but in this case there is a disadvantage in the long learning period and the lack of feedback from the real person. We can also study with the tutor remotely and be more confident in the material, but this way is more expensive than the first option and its effectiveness depends on the teacher. From my point of view, another option is the fastest and most efficient, but also the most stressful and difficult, is to go live in the country with native speakers.
