Even though I have had problems with other language programs in the past I was able to complete all of the lessons in units 1 and 2 fairly easily. However, I found it difficult to remember what I had learned outside of the context of replying to the speaker in the lesson. Someone asked me what I had learned and to my amazement I could think of no reply.
There is one male non-Japanese speaker whose Japanese is very hard to listen to. He makes mistakes and has a terrible accent. I found that frustrating. I also wish there was much more opportunity given to actually speak. Some drilling of words and phrases would be fun. Lots of information was given but little opportunity to use it.
