yeah man, you got to apply early. These days, applying early seems to be the norm, so the advantage is really all that much. Its the disadvantage of applying later that will get you. My suggestion, send AMCAS as soon as possible. With the secondaries, get them out as soon as you can, but make sure you put time and effor, or will all be for not!
by the way, I got this info. from the forum, as I am applying this summer as well! I wish US luck!
