From what I can tell, there are two seperate Japanese courses made by Memrise. One has a purple thumbnail, and when I search japanese on the android app, it is the first you see. The other has a pink thumbnail and is the first course you see when you search Japanese on the web browser. It looks like the pink thumbnail version has more words available, but I am well into the purple courses (currently 3/4s done Japanese 2). Is there really much difference between the two courses? If so, is it possible for me to transfer my current progress from the purple courses to the pink courses, or should I just start level 3 as the pink course?
