Thank you very much for viewing. Regarding the Spring Seminar Math textbook, it has been copied, so there are no markings. However, it is a used item. Please check the photos and understand this before purchasing. As a bonus, I will include the Spring Seminar Science and Social Studies materials. Please let me know if you don't need them. I apologize, but I have lost the answer key for Social Studies, so the answer key will only be for Science. I will carefully inspect the items before sending them, but there may be oversights. Please consider the above, and refrain from bidding if you are overly concerned about the condition. No claims or returns, please. Thank you for your understanding. Yotsuya Otsuka
