Hi Turtlely,
Before you leave any part of the Business School application blank, you should first make sure that that won't cause other problems for you later on. Since you're ultimately asking an Admissions question, you would likely find it beneficial to speak with an Admissions Expert about your situation, profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/You might also consider reaching out to the Schools directly to ask. Each School's Admissions Department would likely be happy to answer any questions that you have - and they can help you to avoid making an accidental 'mistake' with your application to that School.
