Hey Dutchers,
710 is a good score, so I would not worry about the quant section. As you are an engineer, it showcases that you do have a quant background so that helps as well.
However, you have mentioned that you have done your Bach. as well as your masters in Civil Engineering. You would need to justify why you want to shift to finance after such an extensive experience in engineering, especially for schools like LSE and HEC which are extremely selective and are known to pick only a handful of students from thousands of applicants.
I would strongly suggest you to have more school options.
I also recommend you to not retake the GMAT ( since you already have a good score), instead focus your time and energy into building your profile and working on your application.
I would suggest you to get some finance experience on your resume ( Certifications like CFA , quality internships in Finance would help).
Secondly, your essays will have paramount importance in justifying your reasons to shift to finance and explaining how you plan to use the degree to fulfill your long term goals. So make sure that you spend enough time on your application.
