I hope it is okay to post this here. I'm trying to organize my stacks of Japanese learning material organized.
I purchased Tanki Master Nihongo Noryoku Shiken Drill N2 (短期マスたー。日本語能力試験ドリル N2）. It is a thin yellow book of practice exams. It has an answer key and listening CD. I took some notes in pencil that are now all erased so it is used but still usable.
