|If you're a student, Umich provides classes.
|Washtenaw Community College offers classes.
|Private tutor with textbook. Going through a textbook with a tutor is a great way to learn. I'd recommend searching Google. If cost is a concern, there are many Skype lessons available with teachers in countries such as Guatemala or Venezuela. Preply and Verbling both offer online tutors.
|Duolingo or Rosetta Stone. It's very difficult to start with a tutor if you're a beginner. These programs help to get started.
|Netflix. There are lots of great Spanish language programs on Netflix. This is particularly useful in understanding accents from different regions.
