I have reached the decision that I’ll either not have an N3 list of words and kanji (there are no reliable sources, those that are free are made up of guesses that are too wild for my taste), or I’ll make my own list based on kanji/word frequency data and my own wild guesses (=experience with the language, though only through the internet, TV and novels).
There is a slight problem with frequency data. It was based on frequency of words in newspapers, ignoring general usage (which is probably way too difficult to measure). Though that might be an advantage regarding the JLPT.
UPDATE: I don’t believe that the results would change drastically, so this poll is closed! If you missed the voting but would still like to tell your thoughts about the question, please write a comment.
