nope that is just the basic of Japanese and here is a site that i found that taught me alot, u must check it out!!! That is where I learned my Jap.
www.japanesepod101.com u can download the lessons onto ur mp3 player and listen to them or listen to them online. The lessons r free but if u want more help like course outline and stuff u need to pay for the membership. Well i think for ppl that have Ipod or Ipod Nano is realli lucky cuz these lessons also show the main words that the lesson is teaching about and it appear where the space u put the lyrics. And for the different writing of japanese, i think that part the hardest of all. Well i'm trying to master Katakana and Hiragana so I will get better after practice!!! Ja, sore dake desu, mata ne!
