Hola amigo. As of April 2019, I am taking an introductory class on Spanish. The book for this class is titled "Spanish Now!", Level 1 Eighth Edition published by Barron's Educational Series, Inc. ISBN-13: 978-0-04380-7523-5.
One way I am learning Spanish is to use a web-based flashcards system I am developing. You can view the flashcards sorted by unit (the units in the book), or by the Spanish entries.
