The book is very good, it has no cuts or anything. The code is unused. It contains solutions and expressions that the doctor used to give us 🔴 I'm selling you the book with my help in anything you need with the book, or with the doctor's method, or even how the questions are and what they focus on. Meaning, I will try to help you as much as possible. The book I bought it for 370. I'm selling it to you for 250 as an appreciation because we are students. Contact only if serious 🙏🏻 And the price is negotiable if you are a student and your circumstances are difficult.
