I took the first eight GS tests getting ready for the Sept. 12th date, then AAMC #8 and #9 right before Sept. 12th as gauges to what my real score would be, but I ended up deciding to reschedule to Oct.21st, and I had the final two of both GS and AAMC tests left. So then I took the last two GS tests first, wanting to save my last two AAMC tests for a final assessment of where my score would be on test day.
People do lots of different things with full lengths, but honestly I can't see the point in taking them faster than once every other day, and even following a schedule that packed with full lengths seems unlikely to produce real improvement. I would take it one day, maybe review and/or look at the answers I was curious about a little bit, but not too in depth, THEN take the next day to really scour over it, taking notes, looking through my scratch paper work for errors, and so on. That's the fastest I ever took them anyway, and I can say in hindsight that I would have undoubtedly profited from slowing down on the full lengths and taking more time to actually master my weaknesses. I would just kinda take notes, realize why I got wrong what I got wrong, and move on. However, that's not enough to fix a weakness, you need to run extra passages, extra problems, etc. on that weak area to make sure you know the topic inside and out; that's what turns a weakness into a strength, not just looking at the answer and realizing what you did wrong.
If I had known what I know now about preparing for this beast, I would have taken about half as many full lengths and spent the extra time actually mastering my weak points. You'll notice that taking a bunch of full lengths and reviewing the way I've described didn't actually do *anything* for my scores, and some people even take them at a faster pace than every other day: I hit a 35 by my fourth AAMC attempt, and yet another 14 full lengths (!!!) didn't do CRAP for my scores, even though I would spend an entire day and a half reviewing my errors on each one. You have to actually go back to content review and figure out why your weaknesses are what they are, what fundamentals you're actually uncertain of, building waaaaay back down there from the foundation all the way up through passage work and extra problems, then finally back up to full lengths, to really fix problem areas.
Ha! Listen to me ranting. Prepping for this has taught me a lot about how to study - even if I never went to med school I would have learned lessons while studying for this test that I will be able to apply to problem solving in all kinds of different areas in life. Summer '14 was a hard but good jnnjsummer!
