Hi yashrajrathi20,
A 710/Q49 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. As such, a retest is probably not necessary. Depending on the Schools that you plan to apply to, you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement (and the more time that you have to act on that advice, the better). There's a Forum full of those Experts here:
