I just recently took my commercial single with multi add-on check ride in one afternoon. That's no big deal except that I did all the multi training in a BE-95 Travelair during the 2 hours before dark the previous evening and then again in the morning for 1.7 in a different BE-95 and then had to take the checkride in yet another BE-95 a few hours later. I was scared sh**less! I nailed the checkride I guess because everything was so fresh in my mind and I felt like being shifted between 3 different Travelairs (Switches, avionics, etc.. inconsistent) was a reasonable thing to be nervous about. I just gave it a go and was pleasantly surprised.
Ona different note:
One thing of interest that minitour mentioned was thinking about UNOS over and over during his vacuum failure and compass turns.
BEWARE!! I failed my instrument ride because that was the only way I was used to doing it. My DPE took my gyros 5 miles out enroute to a hold to enter a VOR approach. The VOR was on the edge of a lake on a windy bumpy day for the appraoch into AND (Anderson,S.C.). With the continuous light and moderate chop the UNOS (which I was a master of) just wasn't working out. I ended up on the wrong side of the hold without realizing it! (That will also happen if you try a straight-in when you should be entering parallel, just when you think your rolling out for the outbound leg you're actually crossing directly above the VOR fix and will probably miss the split second CDI switch)
So, food for thought, know when to TIME those turns instead of UNOS and be very carefull about entering holds properlly when it's windy. I entered straight in instead of parallel because I used my heading indicator instead of true course which until this day, I don't know a good way to determine true couse quckly in IMC in a low tech plane.
You surely are going to stamp your name all over that place if you pull it off, surely it hasn't been done more than once before!!.
