I still felt a little nervous on roads where I was going more than ~30mph, but I was routinely in the lefthand lane on major roads and didn't feel nervousness about the oncoming traffic (well, I sort of felt it, but it was sort of like there was a wall separating me from that feeling).
I was fine pulling into parking lot spaces, but less good pulling out, so that's probably worth practicing -- and FCS-Ian wisely suggested consulting the driver's manual about the official most correct way.
On reflection, I'd also like to pratice 3-point-turns and parallel parking once more before I actually take a road test.
I feel like I'm a (at least) minimally competent driver at this point (and FCS-Ian continues to be mostly wholly unworried while I'm driving), but I'm not sure how stickler/demanding the instructor will be (despite trijinx's assurances that her road test was "basic and boring," I'm still partially convinced that I'm going to fail my first road test).
Edit: I went online to schedule a road test for over the Christmas Break and apparently the next available road test is January 27 in Cambridge -- I don't even know when the next one in Watertown would be. :/
