Which resource can significantly improve quantitative reasoning skills for the OAT?

Improving quantitative reasoning skills for the OAT requires a focused approach to practicing mathematical concepts and problems. Math problem-solving workbooks are specifically designed to provide extensive exercises and solutions that enhance a student's ability to apply quantitative reasoning in various scenarios. These workbooks typically cover topics like algebra, statistics, and calculations relevant to sciences, all of which are integral to performing well on the OAT.

While textbooks on biology might provide a foundational understanding of biological concepts, they do not directly contribute to improving mathematical or quantitative reasoning skills. Similarly, online video tutorials can be beneficial for visual learners and can help clarify concepts, but they may not provide the level of practice or engagement that workbooks do. Flashcards for scientific terms are useful for memorization and understanding terminology, but they do not address the need for practice in quantitative reasoning specifically.

Thus, math problem-solving workbooks stand out as the most direct resource for cultivating the skills necessary to tackle the quantitative reasoning component of the OAT effectively.
