I've decided that an MBA is my best option. I have a liberal arts degree and have had difficulty finding a job with promise. My current job sucks, and, after 2+ years, I've gotten very tired of the limited advancements opportunities; I'm planning on quitting very soon.
In my free time, I'd like to start prepping for the GMAT. Previously, I tried the Knewton
online course, but I lost motivation after approximately 2 months of study. What strategy/materials/courses have you used to maximize study time and motivation? How long do you suggest prepping for before the exam?
