Thanks for sharing your profile, few things to focus on:
1)Work Experience
-Get some solid work experience with a focus on driving impact/results and developing your interpersonal skills.Your work experience is really important in the admissions process so this should be a key area of focus for you
2)Extra-Curriculars
-Get involved in things outside of work that you have some passion for. In particular focus on gaining leadership skills here and gaining some depth/breadth in a few different areas
3)GMAT
-You're applying from a really competitive pool so you will need to do your best to achieve a high score, once you sort out some of your target scores, aim to exceed the avg scores
4)Self-Reflection
-spend some time thinking through what you're looking to gain out of your MBA experience and how you need to develop
5)Research
-Do your school research so you are not just basing your school list off of the rankings
