Difficult School Past Exam Series Tohoku University English 15 Years, 8th Edition Thank you for viewing. There were a few light markings in the problem section, but they have been erased. There are traces of underlining with a ballpoint pen in the answer section. Other than that, I have checked each page, but please forgive any oversights. Thanks to this problem collection, the person who used it passed Tohoku University. May this connection reach the buyer... ! Shipping costs will be covered by me. Thank you very much.
