Hi Magicien99,
If you only recently sent in your Round 2 applications, then have you received any responses yet from the Schools that you applied to? You're ultimately asking an Admissions question, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans (and applications so far). Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement. There's a Forum full of those Experts here:
https://gmatclub.com/forum/ask-admissio ... tants-124/1) Back in November, you noted that you had taken the GMAT 3 times. How did you score on your more recent attempts (including the Quant and Verbal Scaled Scores for EACH)?
If you're interested in taking a free practice GRE, then you can do so (you can access 2 for free from
www.gre.org). You might consider working through some practice questions before taking that first practice GRE though.
GMAT assassins aren't born, they're made,
