Learning japanese by yourself (link recommendation)

1. Learn kanji from kanjidamage.com
Learning kanji? This one is the best site i've ever known. Super recommended.

2. Do flash card exercise (making your own flashcard) from cram.com
For free!! You can export to quizlet. Why quizlet? Becauze once you have quizlet card, you can convert your flash cards to kindle :)

3. Convert your flash card and read it using kindle (http://kindle-convert.bixly.com/)
Tadaaa...

4. Studying grammar
I have at least two favorite places:
- maggie sensei
- jgram
