One strategy that really helped me was reading the question carefully, breaking it down into variables and equations, and then starting with the answer choices during practice to see if they could be used efficiently. Give yourself a rough min-max range to test how the options fit. Manhattan recommends a strategy where you start with option B, then try D, and narrow down from there. Since answer choices are often sorted, this approach helps you quickly gauge whether you're moving closer to or further away from the correct answer. It gives a smart way to zero in on the right choice efficiently. If the options don’t work directly or seem too time-consuming, only then move on to solving it algebraically.
Over time, I started noticing recurring patterns that offered quick clues about how to approach different question types. I get that using answer choices first doesn’t feel intuitive for many students but for GMAT specifically, I genuinely believe it’s the smarter move. It can save you valuable minutes, especially on tougher questions (helped me on couple of hard ones in my real test) or when you’re short on time and need to make a strategic guess. So I’d say it’s absolutely worth training yourself to use this method.
