I use the 7Sage proctor. Right now I have it set to "Gayle" she sounds almost exactly like the proctor the first time I took the LSAT. Not sure if that's a good thing though. I need to adjust to using a watch.
Yes... there was no 'break' between sections during the test... the proctor calls time... then asks you to turn the page... at least that is how it was with me.
Just have a friend be the proctor in return for a meal. And you can get a 5-section PT (the experimental pulled from an earlier PT) from Cambridge for $9-10ish.
Depends on your proctor. I got shafted once and given a warning for bubbling in a completed answer after the proctor announced to put our pencils down.
The best they can do is give you a refund so you can retake it. Unless proctor/testing center is absolutely egregious, nothing else will change -- at least from what I've heard.
