I will be listing some of my personal problem sets for job hunting (March 18th). The cover is damaged, but the contents are generally in good condition. The main book is the newer version of the essay problem set, but I'm including the older version by the same author as a bonus since I already have the problem set. I had a name sticker on the green book, but when I tried to peel it off, it made a tearing sound, so I left it as is. The bonus book is old and quite damaged. I will also be listing other essay reference books by Yuichi Higuchi.
