QUOTE: A lot of people give themselves 30seconds-2 minutes between sections, which is absurd. You only get like 10 seconds between the sections, or you should train for that.
Are you sure about that? I've read that you get 'about a minute' for allowing for the proctor to read the directions.
Also, I've at least some of the people do take practice tests with an extra psuedo-experimental section. I find that it really helps. I'm more confident about my rhythm and pacing. I've got more tests than I can handle, so I usually use a LG section from '10 Actual' as the first section.
I've been giving myself 60 seconds after sections 1, 2, and 4; and then 15 minutes after section 4. By the time I start the writing sample, I'm tired as hell, but I feel like I've actually prepared myself, as opposed to just studying old tests.
