24,676 PointsHow does Extra Credit works?
Hi Im in the Swift Basics Course, and I just finished the Operators stage.
In the course page I just saw an item at the end of the stage called "Extra Credit"
Well it said "Using the math operators taught in this stage create a formula to change any given temperature from Fahrenheit to Celsius"
Well I just easily did it in my xCode, but now I do not know where to upload it, I thought it was gonna give me extra points for make the task, but I do not know where to upload it.
Thanks for your help

33,856 PointsHey Sebastian, the extra credit is additional to what you've learned, but you don't actually receive any points from that.

5,285 PointsOh, I see... the extra credit is just on our own. I thought maybe we do it on the workspaces.

12,117 PointsIs it possible that the extra credit gets highlighted like the others that you have finished?

33,856 PointsHey, Edmund. Extra credit is optional and not recorded by Treehouse. It's an initiative for students who are interested in applying what they've learned. I know it seems like it could get highlighted; however, it's an optional step where no credits are received. Hope that clears it up a little for you.
