Listen to Diego as many times as you need without reading the text . When you understand better, listen to him again following the text, trying to fill in all the gaps and pausing when necessary. When you have filled in all the gaps, press "Check" to check your answers. Use the "Hint" button to get a free letter if an answer is giving you trouble. You can also click on the "[?]" button to get a clue. Note that you will lose points if you ask for hints or clues!
