The Low Hanging Fruit
The "low-hanging fruit" is a phrase often heard in business circles, because it's a good guideline for an investment context. The low hanging fruit is easy to reach. If you pick those easy pieces of fruit first, then conceivably you might be full before having to do any real work. That's state of events is characterized in business circles as a high return-on-investment.
In a GMAT context, return on investment, or ROI, is also a useful guideline for studying. For example, nearly none of the GMAT course providers sufficiently differentiate their product offering. They do offer group classes and tutoring, which is a kind of product differentiation. But they do not create separate classes for MBA and Masters tracks. And this choice has an effect on the ROI of those courses. For the course-provider, the ROI is elevated, because they can sell the same product to more customers. For the student, however, the effect on ROI is negative, since they have to spend class time on issues with little personal relevance.
