The service provided by JapaLingo, which focuses on writing, is exactly what I am looking for!
I have been studying Japanese for a while now, and I'm trying to see if I can express myself well in the language. In particular, I would like to see how I score in writing. However, if there's nobody to correct me, there's no way I can understand and improve. While there are many schools or online courses focusing on grammar and conversations, the service provided by JapaLingo, which focuses on writing, is exactly what I am looking for. While there is a deadline for every assignment, I can do it at my own time and pace. And I think the teachers really have taken the time to correct my assignments, as they have given me detailed explanations and comments. You will be amazed that, after having learned some amounts of grammar and words already, you can still make a lot of mistakes. And you don't really know the meaning of the words if you are not using them for real.
