This is a complete pack prepared by professionals Vaughan for students of all levels. These books are one of the key elements of the methodology of Vaughan Systems. This pack includes 3 Translation Booklets, a quantity of material in English focused on progress with the structures and vocabulary through the language. A disciplined study of them will provide much greater ease and speed in English. Served with 3 audio CDs with all the English phrases are translated into Spanish. The best way to work the book is to focus on a single list, repeat it several times and even memorize it until you can say phrases in English, as fast as in Castilian. We always recommend to go from less to more, ie, from beginner to advanced levels. The first four books (1, 2 3 and 4) contain the basis of 90% of the words and structures used in everyday English. Remember that you do not speak a second language until they can reproduce their structures with flexibility and spontaneity. These books will help achieve that freedom, and finally managed to spoken English.
