Hi there,
Congrats on the 740, that is quite strong given it's above the average at any business school in the world.

Generally when you are at that score level, additional points are not going to be the deciding factor... instead it will be all of the OTHER components of your application... especially your work experience, leadership, accomplishments, recommendations, personal stories and motivations shared through your essays, interviews, etc. You are on the less-experienced side of applicants so you'd want to show that your QUALITY of experience has been strong during that timeframe, and why NOW is the ideal time to apply vs waiting a little longer in your career. Lots to think about, keep us posted!
