Sure thing britt.
I think whoever you talked to at Penn Foster did not read the instructions for the Oleson Village project or he never would have suggested converting the coordinates in the first place. The project really hasn't changed much over the past three years or so and a few of us here that have done it know first hand that the coordinates work just fine as shown.
By the way, I don't think that is the PDF for the Oleson Village project. It looks like it is for another civil project that involves contouring. Maybe the same one Wendymoose is working on right now.
