Unfortunately only 4 stars. because I had to wait almost 4 weeks on the book :( I have contacted the seller and I got quick and good help. The cart Check reimbursed me which I find very positive, now the book has finally arrived. It is in a very good state, minimally one sees that it has been used. I personally think it's not too bad, it is a paperback and not a hardcover. My expectations were therefore exceeded. To book per se. I study chemistry and my Proffessor rejects his lectures almost exactly to the Atkins! So for me, the book is perfect for pre / rework. What also made me very happy is that the book contains exercises and solutions!
