My son is on an Engineering course at College, a teacher lent him this book for a couple of days. After he returned it, we decided it was such a helpful book that we'd buy him his own copy. He says its been a godsend, it has everything laid out well and has all the information at his fingertips.
Arrived within the specified time and in good condition. My son finds it an invaluable aid to his college course. I can't be too specific about its contents but he says it has helped him alot. Happy with the product.
