Para vs. Por

I am confused about the grammer rules regarding the use of por and para. Im not sure what to use when. Any feedback will be appreciated. Gracias :roll:

Hi. Yes, por vs. para drives me nuts, too. And I'm not alone--had you searched the forum, you'd probably have found the following thread, which deals with exactly the question you asked: *__http://www.rocketspanish.com/bb/viewtopic.php?t=93__* In addition to this useful thread, I'd recommend the Rocket Spanish Advanced Book, which devotes section 3.5 to POR VS. PARA. ¡Buena suerte!

One can also log on to: https://www.rocketlanguages.com/spanish/, click Spanish Grammar (under Free Spanish Lessons), then scroll down to Prepositions Part III: POR and PARA. It also may help.
