It is good to have a language partner if you have a food one but it is not easy to find. You could have people there looking for a couple or something strange so remember to protect yourself. Moreover, language partner is not a teacher and most if them could tell you the way to improve your English more fluently and it could be a disaster if you two dont have a common language which is able to help you explain the language to your partner efficiently and this will make you spend a lot of time on guessing if you are right! Language partner is best for someone with a good function, i can say immediate level. If not , find a teacher , this will save your money and time
