This is "The Study Methods You Shouldn't Do" by Takashi Ishii. It clearly explains why you're not seeing results despite studying, and how to memorize things efficiently. I've read it a few times, but there are no markings or stains. It includes the cover and obi, and is in overall good condition. Please only purchase if you understand that it has been stored at home! Instant purchase is welcome. I will pack it carefully and ship it!
