With over a decade of experience in test preparation, including my current role as an instructor and coach at Target Test Prep, I specialize in helping students achieve their GMAT goals. My journey began with a 99th percentile GMAT score, which led to my selective hiring at Manhattan Prep, where only 99th percentile scores are considered, and 7% of those are chosen. Since then, I've coached many individuals, guiding them to improve their scores and gain admission to top business schools. My approach is rooted in authenticity, humility, and expertise, as reflected in my average teacher rating of 3.95 out of 4. Let's work together to create a personalized plan to conquer the GMAT and reach your dream school!
