Open up the Rosetta Stone program. You will be presented with the "Menu" screen, which is used to access the different lessons and products you own. Click on the "Spanish" option from the "Language/Product" column on the left-hand side of the screen. Select your desired product from the drop-down menu. If you're just starting, this is likely to be "Level 1."
Choose the desired unit from the "Unit" column, which is located just left of the center of the screen. The units are numbered, and the tabs each have a grid of four squares on them. After clicking on your desired unit, the lessons that are contained within that unit will appear in the center of the screen. There are between five and 12 lessons in each unit. Click on the lesson you wish to take, and you will be taken to the "Activities" screen.
Select your desired "Language Skill" from the options on the left-hand side of the screen. Option "A" focuses on listening and reading; option "B" on listening; option "C" on reading; option "D" on speaking; and option "E" on writing. It is advised that you use a combination of these skills to efficiently learn the language.
Click on the "Exercise" that you wish to take. There are four exercises, located in the center of the screen. After you've clicked on the exercise, you will be taken to an individual exercise's screen and presented with an exercise revolving around your chosen skill. Press the speaker icon to hear any text spoken aloud by a native speaker.
Click on the "Preview" button to see the solution to the selected exercise. This button is shown by a magnifying glass icon and can be accessed on the "Activities" screen and the individual lesson's screen. On the "Activities" screen the button is located toward the top of the screen, and on the lesson screen it is located to the right-hand side of the screen.
Select the "Guided Exercise" option, located to the right of the "Preview" button on the "Activities" screen. The "Guided Exercise" option takes you through the "Preview" of the chosen lesson, and then you have to complete the exercise as normal. If you get anything incorrect, the program will return to that question later on.
Navigate through the remaining lessons in the same way. Working through the lessons in this way is the main operation of the Rosetta Stone Spanish program.
