Resources/Textbook
I have the following college textbooks for those already in possession of these books:
Puntos de Partida, 7th edition, by Marty Knorre
Impresiones, 1st edition, by Dr. Rafael Salaberry
I also have the following Spanish Resource books. . . :
Gramática para la composición, 2a edición
. . . and will work with the following books (While these books lack colorful photos and are less appealing than college textbooks, they are a cheaper option for those on a budget or for those not enrolled in Spanish courses):
Spanish Grammar the Easy Way, 4th edition by Boris Corredor (Cost: under $15)
Advanced Spanish Grammar: A Self-Teaching Guide by Marcial Prado (Cost: under $15)
Spanish Grammar (will add link soon) (Cost: approximately $10)
