GMAT Quant questions can look intimidating—but the hardest part is not always the math.
In week two of our six-week GMAT study series, GMAC Zach is joined once again by Hailey Cusimano of Menlo Coaching for a hands-on Quantitative Reasoning session. Together, they work through three challenging problems and explore what actually separates an efficient GMAT solution from a long, calculation-heavy one.
You'll learn why rushing into the first available approach can cost you time, how to identify the question's true ask, and how techniques such as number picking, visual organization, and proportional reasoning can reveal a much simpler path forward.
Along the way, Hailey explains how to:
- Front-load your analysis so you can execute more efficiently
- Identify and pursue the path of least resistance
- Recognize the cues intentionally built into a question
- Choose useful numbers when variables make a problem difficult to visualize
- Avoid doing the right math for the wrong question
- Turn "careless mistakes" into specific opportunities for improvement
Whether Quant is your biggest concern or you simply want to become a more flexible problem-solver, this episode will help you approach difficult questions with greater clarity, confidence, and control.

Key Takeaways:
- Analyze before you calculate. A small investment of time at the beginning can prevent you from spending several minutes on an approach that will not pay off.
- Look for the path of least resistance. The first method that comes to mind is not necessarily the most efficient one.
- Treat every detail as intentional. A word such as "remaining," "integer," or "non-negative" may completely change how the question should be interpreted.
- Make abstract questions tangible. When a problem uses percentages and variables, choosing useful numbers can make the underlying relationship easier to see.
- Answer the question that was actually asked. Correct calculations can still lead to a wrong answer when you use the wrong comparison or percentage base.
- Investigate so-called careless mistakes. Errors often begin with how the problem was interpreted or organized—not with the final arithmetic.
