Hi James,
Your doubt is perfectly valid here since the English translation doesn't change, but the Spanish structure does. Actually what happens in the second sentence is that it is not expressing a real future in Spanish, but rather an immediate action. Sometimes you can use a present tense in Spanish to express something that you're planning to do right away. So to translate more precisely, we could say:
Voy a llamar a Sandra = I'm going to call Sandra > near future
Yo llamo a Sandra (enseguida) = I'm calling Sandra (right away) > immediate action
To avoid further confusions, we'll make sure the translation in English matches -even if it's not the most natural- in the next update. Thanks for pointing out this issue and enjoy the rest of level 5!

Hi Tismert,
You can find a summary of all the material taught by level in the main menu of the software when clicking on the "Global Index" (at the top).
There isn't a specific part on sentence structure though, as this is something we work on throughout the program progressively, and as it depends on each situation.. (describing, comparing, commenting etc)
Hope it helps..or maybe you're looking for a specific structure? Let me know if I missed your point here 🙂
