Same here. I am in this constantly oscillating mental state of "Oh crap, it's in a couple days...what don't you know? Go learn it!" and "You've been studying for 15-20 hrs per week and know your references...have confidence and you'll do better with a clear mind."
As I'm sure most understand, I'm struggling with the fact that they COULD ask anything and the potential of not doing any similar practice problems, etc. It's like I'm intentionally finding weak areas and focusing on them. Stupid at this point. I need to just feel good about my prep and trust that I will "engineer" my way through the exam by knowing references and finding what I need to.
I feel like for me, it's just like giving a presentation or running a meeting. I have to have a certain level of internal confidence to be calm, have a clear mind and perform at my best. Unfortunately, a lot of that "confidence" comes from telling myself it's no big deal. Basically, down playing it to remove stress. To counteract that, I am having a hard time telling myself, "Oh, relax. You got this. Don't worry about it!" But, if I can get to that point, I perform so much better while calm.
To finish out the last couple of days, I am planning on reviewing some problems this evening (NCEES practice tests, etc.) and getting my stuff organized. Tomorrow I am working from home in the morning and then traveling to the hotel for the evening. Will get there early enough to get in and settled, get a nice dinner and get to bed early. If I look at anything PE related, it will probably just be to settle my mind about knowing references, etc. I won't be looking at any problems or trying to learn new material. Who knows, I may try to not look at it at all. I guess it will depend on how I feel tomorrow night.
Good luck to us all. Just remember, it's not the end of the world if you have to take it again. Lots of great engineers have.
