Honestly being "apathetic" is the best way to prepare yourself. Check my post history, I have had my fair share of freak outs and tantrums about this thing, and I'm a grown ass guy! I know I put in 2 months of my time and studied hard. I know that I am lacking on my PAT ability but it is too late to change anything. I've been doing good on my practice tests, so what is there to worry about anymore? At this point, I am excited rather than nervous to take the test. I remember a few weeks ago I was PMing every single forum member for their opinion looking for support and validation on how it would be possible for me to improve my QR score which I was getting 15's on. Now, I scored 3 back to back 19's on my bootcamp tests, and went from a 15-18 on the previous 4.
In short, have some confidence. You will never be ready, it is just likely that you can handle it with your preparation. Don't open a single book tomorrow, I will be doing the same Monday (test Tuesday). Take the day off, go to church if that's your thing, have lunch with the family, clear your mind, and be well rested for your test Monday. You can, and you will do it. You know more than you think! (I hear this from everyone who takes the test nervous)
