The book's condition is excellent, but there are two minor folds on page 30 and page 194. It is unsolved except for the first few pages of the book and a few pages of mathematics in pencil, and I have confirmed that they have all been erased. The supplement is completely unsolved, God willing, it will benefit those who will take the paper exam because most of the questions in it are from the paper exam. Delivery is in person or shipping is on the buyer.
