Purchased in 2022. I used it a little, but due to pregnancy and childbirth, I haven't used it and it's been sitting around. I'm selling it as I'm decluttering. If you want to see the trends of the questions, why not check out these slightly older reference books at a low price? *Both the first and third booklets are detached. (See image 5)* *There are some notes in the problem set. There are orange pen markings on the questions up to the first 20 pages or so. (See image 3)* *Shipping will be via Yu-Yu Mercari. It will take about a week to ship. Thank you for your understanding.*
