Dear labatmolso,
Your GPA will not hold you back, but you do want to make sure your other application components are strengths for you. In other words, give the admissions committees plenty of reasons to want you in the class, but no reason to pass on you. I also encourage you to submit an optional essay or additional statement if given the opportunity on your undergraduate performance. You will want to note your lack of focus the first two years, and then use the bulk of the essay highlighting the evidence you are focused, motivated, and capable of excelling in business school. Your performance in your last 2 years, your graduate coursework and your GMAT score are all indications of your ability in that regard.
Good luck,
Lisa
