Nontraditional undergraduate students are now mostly enrolled in post-secondary education institutions and must be adequately prepared for college-level math. The problem addressed in this study is that nontraditional undergraduate students need to be sufficiently prepared for college-level math placement entrance exams. The purpose of this qualitative case study explored the experiences and options available for nontraditional students to better prepare for college-math placement entrance exams. The study's population consisted of nontraditional undergraduate students who had taken a college placement entrance exam. The theory of self-efficacy framed the study where semi-structured interviews investigated the experiences of 10 participants who had taken a college-math entrance exam. The research examined the experiences and resources used by nontraditional students to better prepare for college-math placement entrance exams. The study's results provided insights from nontraditional undergraduate students' perceptions of their preparation and experience regarding a college-math entrance exam. The study revealed the themes of college entrance exam preparation, math anxiety, college entrance delay, and college readiness. Recommendations for practice include the development of literature to explain the testing process and expectations of college-math entrance exams, together with a list of test preparation materials. Future research recommendations include a larger participant group who identify as a nontraditional student and determine if the length of time between high school and college plays a role in college preparedness. Defining the challenges and opportunities from a nontraditional undergraduate student perception is necessary, and adjustment in the strategy and resources available to promote improved college readiness, increased college-math entrance exam scores, and reduced math anxiety, thereby increasing one's self-efficacy.
