Grammar is not the goal.
For most people, the goal is not to become a grammar expert—the goal
is to be able to speak Spanish conversationally. To do that, you need a
complete conversation course.
Camino del éxito
is the only course that is fully integrated with the material on this
website. By combining Spanish grammar exercises with real conversational
practice, you will much more quickly reach a level where you can
communicate effectively.
And for most people, communication is the primary goal.
