Don't worry about it,
Just add it to the list of i won't do that again.
I managed a hardish landing after selecting the wrong MP setting.
It didn't matter that everyone said it was at night one engine simulated out etc.,and the instructor should have spotted it and not let the situation develop. I still felt crap and useless.
But looking back on it i proberly learn't more from that crap trip than i did in the previous trips. I bet in the future you won't make the same mistake again.
Although its not a standard procedure if i am flying VFR and not using any RNAV beacons i set the wind on the VOR dial i find it easier to judge xwinds etc so if your heading on the approach isn't in the same half as the wind there is something wrong.
