So I did it!
Purchased a voucher to book my exam that is, for 640/816. Used the link on here and finally got a discount email today too, so I only paid $84! Currently waiting on the voucher to be emailed to me, and will likely schedule the exam for noon time to 2PM on Thursday the 29th. The testing center where I go, is usually pretty easy to get an appointment at, so this gives me roughly 36 hours and enough time to start my panic attacks!
I feel like I"m ready, but don't want to fool myself... I"m scoring in the low 80's on the boson practice test, however I still suck at the sims and don't feel I am quite fast enough on the VLSM scenarios. I eventually get there with the VLSM questions, but it seems like working out one of those VLSM design questions takes forever!
I feel like I know the material, but not overly comfortable with it. Maybe it's just me, however I plan to take the exam Thursday, if not only to measure how prepared I am. So I'm off to start covering the DIKTA sections, take the boson practice test again and will probably rewatch a few CBT nugget videos from time to time tonight and tomorrow.
On Thursday I will sleep in, briefly look over my study sheets nothing major, while sitting in the parking lot of the facility about 1-2 hours ahead of the appointment.
Am I missing anything?

Any suggestion?
