As with anything else, when deciding how you want to learn Spanish, the internet is as good a place to start as any. If you look on the internet you will find a wealth of options available to you. There are a very large amount of study systems being sold, some at reasonable prices and others for a small fortune. There are also programs for placement in Spanish speaking countries that allow you to totally immerse yourself in the language. Then there are even websites with free exercises and drills that will help you get started.
Of course everyone’s system claims to be the best and only way to truly master the language. During my research I came across no less than three study systems all claiming to be in use by varying branches of the US government and I am sure that doesn’t even scratch the surface of the number of products making such claims. When you are making your decision regarding how to learn Spanish do your research and take into account the pros and cons of each method and pick what is best for you. Personally, I enjoy the free online exercises, but then again I am just out of college and have no money. However you decide to go about it, learning will not be easy.
