New HBS App/ GMAT questions

<p>I was just wondering how often HBS changes up the format of their MBA application like they did recently. Are the essay questions typically the same, or does each one change every year? Is it a good idea to start thinking about the essay questions now if I'm planning to apply to the 2+2 during summer round of 2013?</p>

<p>Also, how important will the new integrated reasoning portion of the GMAT be in terms of admissions criteria? Im taking it early August and am really just studying for the core quantitative and verbal parts. </p>

<p>Should I retake the GMAT if I score below like a 730 or 720 to be competitive? (I guess the other relevant "number" is my GPA which should be around a 3.9 with an engineering/business dual degree at USC).</p>

<p>Thanks!</p>
