This is the text and review tests for the highest level science course for 6th graders at Kigaku Academy. The review tests range from No. 0 to No. 40. The answer sheets are also included! This is a single item listing. It's rare to find a complete set of review tests. - All 4 volumes of the problem sets and 4 volumes of the answer keys are included. There are writings in the text and answer keys. The names will be cut out. In my subjective opinion, the writings are not significant enough to affect the problem-solving practice. We are very sorry, but we cannot accept price negotiations, returns, or complaints. Also, as I am an amateur, please forgive any oversight in the inspection. We appreciate your understanding if you are purchasing a used item.
