The Physics Subject Test assesses your understanding of concepts from one year of introductory physics on the college-preparatory level, as well as reasoning and problem-solving skills derived from lab experience. If you’re thinking about pursuing a math- or science-based program of study (such as science, technology, engineering, or math), taking the Physics Subject Test is a great way to demonstrate your interests on your college application.
