Which Phase is right for me?
There is nothing better than starting out at Phase One and making your way through all of the content in our system. You will learn new things. Seeing as every non-native speaker of Japanese on our content team — each of whom holds JLPT N1 certification — learned new things while going through the Phase One lessons, surely you will too.
A highly advanced student might be able to argue that they should start at Phase Two, but it would be very hard for 99.99% of students (i.e. 1 in 10,000 students) to justify starting anywhere past that.
