[Profile evaluation for MS in Operations Research/ MIM]

Hi. I'm planning to apply for Operations Research or MEM/MIM/or any other business related degree for my masters studies. I'll be shifting from my Mechanical Engineering discipline. I have not take up any business related courses except for Economics and Professional Ethics. I've also done Optimization during my course work. 

With a 6.8 CGPA and a 318.5 GRE score (V - 157 Q - 157 AWA - 4.5), I'm planning to use my extracurriculars as my main focus during my applications. I've participated in two business case study competitions, one of which I was a global semi-finalist among 40 teams and I've also helped organize a case study competition of my own. I'm also a keen writer/blogger, which has given me awareness on concepts such as personal branding, content management, analytics and preparing a product like a blog.

I wanted someone's take on whether this kind of profile is seen favorably for such programs? 

[Profile evaluation for MS in Robotics/Mechatronics]

I am planning to apply to:

NYU

Purdue

Oregon State University

Georgia Tech

Washington University

UC San Diego 

For an MS in Mechatronics/Robotics. I am doing a four year program in (Hons.) Mechanical Engineering and have done an elective for Mechatronics where I learned control system basics such as state space modelling and bode plot stability test. I've done a project on stability of a Quadcopter using a PID controller and done a simulation on Simulink/Matlab as a group project. My program focused on the basics of mechanical design and simulation using ANSYS and CATIA. I've also written a paper on Quality control but have not published it. 

Aside from my enthusiasm/background for this field, I have a 6.8/10.0 CGPA and a GRE score of 318.5 (V - 157 Q - 157 AWA - 4.5). I've been thinking about whether to let go on this field and focus instead on business/MIM instead but I wanted someone's take on my profile.

I was originally planning to apply during this year's application window for the Fall semester (sometime in December or January, depending on the school and program.)

I am aware there is a lot of room for improvement both in my research experience and GRE scores but can this be managed within a year or two?
