Kon'nichiwa! Welcome to the JapanesePod101.com!
We're glad that you like our products.
I suggest you to start from Beginner Season4 and move on to Season5 and 6.
They are Nihongo dojo series.
Some grammar patterns are repetitive but explained from different perspectives.
If you think that Beginner series are easy, then try upper beginner series.
It will help you to move on to Lower Intermediate series.Season3, 4 and so on.
If you have any questions, please let us know.
Thank you for choosing JapanesePod101.com.
