    Only the best experience

    I've already booked three times with GOi. […] this time in order to pass a German language test at a university in Switzerland. This time I would like to thank to my wonderful teacher Julia K., who always made sure that I'm moving forwards and learning, what I needed to know. She was always prepared and full of ideas of what and how we could learn. It was not only her readiness, but also her personality and dedication to reach my (our) goal, which made our lessons great.

  • TELC with absolutely no stress.

    I learnt German with GOI up to B2. I enjoy the professionalism of the teachers and the flexibility. Maja S. is a wonderful, patient teacher who has helped me prepare to TELC with absolutely no stress. I especially recommend GOI to those who because of travel or work schedule can’t go to face-to-face group lessons.

  • Their teachers are seriously good

    […] Their teachers are seriously good, professionally trained in fields like pedagogy and germanistics - not to mention patient and charismatic. […] I also love the flexibility. I constantly move across time zones and my teacher always accommodates to my needs and I can manage my schedule on the school scheduling app.

  • My C1 Exam

    […] I successfully passed it! I am very grateful to my teacher Doris K. because whenever I doubted my abilities she reassured me and pushed me with kindness and confidence. She trusted me more than I trusted myself and this is what I needed. I can certainly recommend GOI to all those who want to bring the language to the next level. Professionalism, competence, passion and dedication!
