No Surprises on Test Day: Mastering the GMAT's Rarest Problems

A handful of GMAT quant questions never look like anything in the practice sets: a remainder problem phrased sideways, a mixture setup dressed as a word problem, a question that seems to need three unknowns until you spot the shortcut. Marie Bercik, who has coached the GMAT for twenty years and scored a 790 herself, will break down a few of these recurring oddballs. The focus is on spotting the pattern under unfamiliar wording, plus the quick checks that stop you from chasing the wrong approach. An hour won't cover every curveball the GMAT can throw, but it will give you a way of thinking about a question you haven't drilled before. That kind of calm, methodical read is hard to build from a question bank alone.
