Se ha quedado un poco obsoleto y es un poco farragoso de leer a veces. Sin embargo el sistema queda claro y los ejercicios son abundantes e interesantes. Además tiene un resumen al final de cada capítulo que facilita el repaso y la lectura rápida.
This was an okay book with teachings on how to approach a problem, any problem. I liked that it had examples to work out to show what it was teaching. I did get a little bored toward the end, as it seemed to be repeating the same thing over and over again.
