About Judy DaCosta, PhD

With over 16 years of experience as a private tutor, I’ve helped hundreds of students achieve top scores on the SAT and ACT—many earning spots in competitive programs and scholarships. I specialize in SAT Math, ACT Math, and ACT Science, and I closely follow changes to each exam to ensure my students are always working with the most current strategies and information.

I hold a Ph.D. from the University of Medicine and Dentistry of New Jersey (now part of Rutgers University), and I bring the precision and analytical thinking from my academic background into every session. My data-driven approach includes detailed diagnostics, targeted skill-building, and personalized performance coaching—down to estimating the percent probability of seeing specific question types on test day.

Just as important as what I teach is how I teach. I’m known for explaining concepts in multiple ways until they truly click. Students find me approachable, patient, and easy to work with—and they’re comfortable asking questions, which leads to deeper understanding and stronger performance.

If you’re looking for elite guidance, proven results, and a tutor who meets students where they are, you’re in the right place.
