Just a friendly reminder: the postmark deadline submission for the JLPT in Japan this year is Friday, September 12.
Many stores have sold out of packets and are not replacing them, so if you haven't already applied, now is the time.
Other countries are different so I recommend you check the JLPT home page for additional information:

I'll be posting a massive JLPT prep update in the next week.
