My experience at learning from italki Hi fellows! I would just like to highlight some advantages of using the italki system to improve my abilities! By all means, italki is a useful tool to everyone who is interested about learning a foreign language on a different way. I used to learn English on a classic way. I used to attend to a classroom and I even had nice classes with great and enthusiastic teachers. It ended up I studied about 4 years through this manner (from the beginning to the end). That was wonderful! Being able to communicate in English well, understanding and being understood has been rewarding after finishing my course. However, the next steps to go further is still 'improving', 'improving' and 'improving'. Since I have a personal desire to learn English, I am thirsty for more! I found out the italki system and it really blew me away after I had my first thirty-minute class. One of the advantages of the system is the instant feedback I can get from the teachers. They can assess me in real time and point out what I need to improve with regard to my speaking. Another advantage is the possibility to chose teachers according to the nationality of my preference so that I can get lessons by native teachers and get a glimpse of their accents. The best advantage of the italki system is the fact that my availability can match the teacher's schedule so I can enjoy my lessons at the time of my preference and availability. In addition, I do not have to leave my house's comfort to attend to a regular school. What else do I want when it comes to learning a foreign language?
