Thanks for posting. The average GMAT scores of the programs you are considering are ~650 (depending on which school), however because of your undergraduate GPA, I recommend you aim for a 700 on the exam. This is what admissions teams at MBA programs will like to see. Remember that on your application, your highest GMAT score is self-reported, so admissions teams will focus on your best score. There is no harm in taking the exam multiple times if you believe you can improve upon your score.
