I am not sure if i should advertise it here, its a site belonging to a reknowned university, somehow there are no securities around these site, and all you have to do is to click and go in to the URL and you will be able to learn the 6 level of japanese this unversity offer
pm me if you are interested, or if you think its fine to post it here, i can do that too, but i don't want to mess things up for myself
