Good question and excellent response from mikemcgarry. I clicked through all of the links Mike posted and read through the articles. There's some really good stuff in there. +1 for sure.
One thing that has helped me with timing is to write a timing grid in the upper right hand side of my notes. the grid gives you a good idea of how many questions you should have answered given how many minutes remain in the test. i've found that this saves time and mental energy when you are trying to gauge where you stand on time throughout the test. also, i've found that my brain tends to work better if i am a couple minutes ahead as opposed to a couple minutes behind.
the quant grid
5 65
10 55
15 45
20 35
25 25
30 15
35 5
the verbal grid

16 45
