Non-Target > Industry > ? > ?

Hello all,

I would like to move in to strategy consulting (MBB, OW, OC, LEK etc) and study for an MBA (not necessarily in that order).

My question/dilemma is, do I:

A) Study for GRE while working for 3 years (total of 3 years work exp. required for most MBA's) > study for MBA > enter MBB/Consulting post-MBA.

B) Prepare and practice for case interviews > MBB/Consulting > MBA either by sponsorship or post MBB/Consulting if I still want to/if they sponsor.

C) Go for an MA/MSc (cheaper) at good target institutions (most require GRE too) > then go on to MBB/Consulting.

Any advice, experience or immediate thoughts is greatly appreciated.

Thanks in advance.
