Hello, hello!

A got started in the game pretty late. I would probably be characterized as the prototypical intelligent underachiever. After many switches, I finally decided on getting majors in finance and management. Towards the end of college, I realized what I wanted to eventually be a part of (corporate strategy/mangement consulting), yet my low GPA (2.7) and unknown school handicap me. To alleviate this, I do have some solid experience working with non-profits, and I am a great standardized test taker (my aim is 720+ GMAT).

Realizing my situation, I knew I needed to get a job with a top company. Luckily, I secured a position in a leadership development program at a Fortune 50 firm in operations.

I understand that I have a about 4.5 years to situate myself for application into b-school, as it seems this is a solid way to break into corporate strategy/management consulting at a top firm.

The questions are:
How much "hope" does my situation have?
What are some steps I should take to put myself in the best possible place?
Should I consider getting a masters degree to cover up my low undergraduate GPA?
Should I take classes at my undergraduate institution to higher my GPA (over the next few years) to above 3.0?
Should I take classes at a different undergraduate institution?
Since I am currently in supply chain/operations, is there a specific route I should take from here? Should I spend 2-3 years here and try to get into a lower ranked consulting firm? Or try to move into a more corporate role within this company? Or would becoming a manager within some field of supply chain be sufficient?
If I were to get into a top b-school, would getting into corporate strategy/management consulting (MBB) be possible with the low GPA?
Anything else?

Thanks for the help!
