Not sure what school you're doing your 141 through... but having done the Checkride recently, I was more "nervous" about the oral than that actual flight, and it turned out I had no problem with the Oral but the flight was hair raising. I passed, but it was difficult. Not to scare you, but just to give you an idea, and perhaps some things to consider. BTW, I did it all in an C172SP G1000 Trainer without auto-pilot.
My DPE had my plan for a course that we flew none of, then gave me a completely new plan on the spot to plan for that we would fly between 2 airports that were about 20NM away from each other (not much time for setup and re-setup).
Took off thinking we were going to fly the published DME ARC.... and we ended up doing a 5 DME ARC to the LOC approach to minimums, then alternate missed, while enroute to alternate, unusual attitudes, then hold non-standard with a parallel entry, then a Circle to Land touch and go, to an RNAV vector to FAF, Touch and Go, then to the published ILS, Failed my PFD just before FAF. Also all the while, would intermidedtly try to throw me off by asking me oral questions I had to think about while setting up for stuff (i.e. Icing questions, How to Compute RAIM, he even asked where I would go if I lost an engine right there, and also asked me to recite the VOR operating volumes).
What made it the most difficult, was the next to ZERO time I had to setup for anything. The close proximity of the airports to shoot multiple approaches made for a very rushed flight (it seemed). Also, the DPE wasn't a native English speaker (no offense), but at times.... it made it difficult to understand.
In any case, I passed... and it was the biggest sigh of relief I had had in a long time.
