Possibly but the aim of the exercise is to do a literal translation. Not convert it to a phrase that you would say. E.g i would probably say "I am in work tomorrow" but that wouldn't translate word for word to a Spanish phrase
I have no problem with the way this is written in Spanish I just have a problem with the fact that it didn't sound like the actual Spanish words in Spanish. The last two words were run together and didn't sound right.
