Hi pxovela2,
Thanks for posting. With the GMAT, if you believe you can improve your score by 30+ points, we do recommend you take the exam again. The reason is on your business school application, your highest score is self-reported on your application, so admissions teams will focus on your highest score. There is no harm in taking the exam again. If you'd like, MBA.com provides 2 free official GMAT practice exams.
We also have free GMAT tips here:

Cheers,
