Research MBA Programs

Hello, I was recently accepted to the McCombs School of Business at UT-Austin. I will be entering the Part-Time program. I have 4 years work experience, a 3.3 Undergrad GPA in Aerospace Engineering (Texas A&M), currently work as a Software Engineer at Dell, and a 670 GMAT (44Q, 38V). I've taken the GMAT once before and scored a 560 (33Q, 34V), but this time, I really studied hard for the GMAT (Manhattan GMAT).

I really want to enter the world of management consulting at one of the Big 4, and plan to supplement my low GMAT with extracurricular activities (UT Graduate Consulting Club), networking, and planning to switch career trajectories in about a year to a hybrid engineering-finance role at Dell before I graduate. Should I retake GMAT given my profile?? It's been weighing heavily on my mind..

Thanks in advance!
