I've started studying for the lab (using IPExpert materials and Proctor Labs rack rental). It's been about a month and I'm wondering if I'm encountering the same preparation experience others who have passed the exam went through. What has been your experience with new territory? I haven't really done any work with on-ramp faxing, for example, I've researched the syntax and it's pretty involved (especially since the syntax has to be memorized.) How much time did you spend working through lab scenarios, what was your strategy in getting through the tough parts, etc?
