The importance of knowing foreign languages, especially English, is indisputable. Ability to communicate when travelling is one of the pros, nevertheless, in my case I truly profit from C2 course at work. Working at multicultural and global company requires excellent language skills. Thanks to classes with Marta, I expanded my English vocabulary and polished my grammar. Best of all, classes were always engaging and conducted in an interesting way. We had fun while learning! After the course, passing Proficiency is easy-peasy!
