The issue is not effort — it is approach.
The DAT is not a memorization exam. It tests your ability to understand concepts and apply them in unfamiliar situations. This is where many students struggle.
In Dr. Jim Romano’s classes, the focus is on building a strong foundation first. Once that foundation is in place, problem solving becomes much more manageable.
This is what students consistently report:
• Improved conceptual understanding
• Stronger problem-solving ability
• Increased confidence going into the exam
If you are preparing for the DAT or OAT, your study plan should prioritize understanding over memorization.
Core Foundation
Students often ask which DAT study materials are used in Dr. Romano’s DAT preparation courses. Two books sit at the core of the course curriculum: DAT Destroyer and Math Destroyer.
DAT Destroyer provides challenging, concept-driven science problems designed to strengthen understanding across Biology, General Chemistry, and Organic Chemistry.
Math Destroyer focuses specifically on developing quantitative reasoning skills, providing additional targeted practice for students who want to strengthen their math foundation.
Together, these two books form the core practice system used in Dr. Romano’s courses, both online and in person.
