Chris,
As a former major airline instructor and Navy flight instructor I can tell you that none of the pilots I gave checks to ever slipped by the ride without some errors (OK....one). You will most likely make them . The most important advice I can give you is don't look for perfection to the point of dwelling on your mistakes, as they are going to happen! And THAT can screw up an otherwise fine checkride.(have seen it happen MANY times) Try to stay calm, keep your head, and move on.
Did I get nervous every time I had my own checkride ? You bet your a-- I did ! It's perfectly normal
But now, I am retired and no more checkrides... Wooopeee!!! I just fly my Kitfox around,eat lunch,airport bum, drink beer (after flying of course) See...that gives you a goal !
You will do fine !
