Seeking advice- checkride tips

I'm scheduled for the instrument check-ride in a couple of weeks. I
feel like I can perform within the PTS, but I'm a little" rough around
the edges" and prone to at least one stupid screw-up per flight, most
of the time I catch the screw-ups myself and fix them in a reasonable
time.

That said, I was wondering whether the experienced contributers here
might offer some advice for the day of my check-ride. My main concern
is that I might be so nervous that I bungle the easy stuff.

Best,

Terence
