New Por vs. Para Level
I'm still wrapping my head around the difference between both words and from what i can tell, I'm not the only one. I think it would really help people if there was a level specifically for Para and Por, with two levels, one for each word showing all the different contexts each is used in. it would save time and also make it easier to learn something i found pretty tricky. :)
It is tricky. This is a topic that takes a looooong time to get down, and is one of the main hurdles for all learners of Spanish. An extra lesson may help -- but may not help very much, sort of like trying to explain the nuances of irregular preterites or ser v. estar in one lesson. There are several sometimes overlapping meanings of each word. You can sit through two hours of class on the topic (I have, in Mexico and Argentina) and still be confused. Some things just take a long time and much experience, I think.
