Grammar

Hi!​ ,
In the software, we do not provide the rules for placing accents, and there's a reason for that. These rules are based on knowing how the word sounds, so providing them would likely be frustrating. The way the rules work is that you sound out the word, then, depending on where you place the emphasis and which letter the word ends with, you determine where the accent should go.

Here is a link that can guide you through the rules: https://www.thoughtco.com/stress-and-accent-marks-3079562

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!
