Hello,
Thanks for your post!
Based on what you've shared, I would say you have the following strengths:
-Promotion, recognition, and increasing responsibility and impact at work, at an obviously reputable company
-involvement and leadership recognition in undergrad
-some global exposure
-project management & analytical skills
-communication skills as evidenced by all of the involvements at Deloitte that you mention
The following potential weaknesses or challenges:
-undergrad grades as mentioned
And the following unknowns:
-GMAT
-essays/letters of rec/interviews
Overall the main thing to do to balance your grades is, as you said, score well on the GMAT. If you have time some people take a relevant course and aim for an 'A', one other thought. When you say fall 2017 do you mean that is when you would apply or begin or ? But likely sounds like you have some time?
Things are looking pretty good from here though, so wishing you the best of luck! If you'd like to chat further we do offer a free 30 minute consult option at
