Zoe Mackey Exposes How ‘Weed-Out’ Classes Crush Students’ True Passions

Columnist Zoe Mackey’s recent analysis in The Daily Pennsylvanian challenges a pervasive yet under-examined practice in higher education: the use of “weed-out” classes designed to eliminate students from academic programs rather than foster genuine learning. Mackey’s argument, rooted in interviews with educators and student surveys, highlights how such courses—often gatekeeping requirements in fields like engineering, pre-med, and business—undermine curiosity, stifle intellectual growth, and perpetuate systemic inequities in higher education.

Weed-out classes, typically characterized by high failure rates and rigorous, often unrelatable content, serve as filters to reduce class sizes in later semesters. While institutions argue these courses maintain academic rigor, Mackey’s work suggests they disproportionately affect marginalized students—those from low-income backgrounds, first-generation college attendees, or underrepresented minorities—who may lack the financial or social capital to recover from academic setbacks. A 2025 study by the Association of American Colleges and Universities (cited in Mackey’s column) found that students who failed weed-out courses were 40% less likely to graduate within six years, a statistic that aligns with broader trends in student retention crises across U.S. Universities.

The business implications of this practice extend beyond graduation rates. Universities rely on high retention to justify tuition hikes and secure federal funding, yet weed-out classes create a self-perpetuating cycle: institutions blame student “lack of preparedness” for attrition while failing to address the structural barriers these courses create. Mackey points to data from the National Center for Education Statistics, which shows that between 2018 and 2023, the number of students dropping out of STEM programs—where weed-out classes are most common—rose by 12% annually. This trend directly impacts university revenue streams, as lost students mean fewer tuition payments and reduced demand for ancillary services like housing and textbooks.

Critics of weed-out classes argue that their persistence reflects a misalignment between educational goals and market demands. Employers increasingly prioritize adaptability and problem-solving skills over rigid academic credentials, yet universities cling to outdated gatekeeping mechanisms. Mackey’s column cites a 2024 survey of 500 hiring managers by LinkedIn, in which 68% of respondents said they valued demonstrated curiosity and resilience over specific course grades. This disconnect raises questions about whether weed-out classes are preparing students for careers or merely serving as bureaucratic tools to manage enrollment numbers.

Some institutions are beginning to reform these practices. The University of California system, for instance, has phased out mandatory weed-out courses in favor of learning communities that provide additional support for at-risk students. Similarly, Arizona State University replaced its calculus weed-out course with a co-requisite model, pairing the class with tutoring and peer mentorship. Mackey’s analysis suggests these alternatives are not only more equitable but also more cost-effective in the long run, as they reduce attrition and improve student outcomes without sacrificing academic standards.

Yet resistance to change persists. Faculty unions in some states have opposed reforms, citing concerns about grade inflation or diluted rigor. Mackey’s column frames this debate as a clash between traditional gatekeeping and modern educational equity, urging institutions to reconsider whether their mission is to sort students or to educate them. The economic stakes are clear: universities that fail to adapt risk alienating prospective students and facing scrutiny from accreditors and policymakers increasingly focused on outcomes over processes.

As higher education grapples with rising costs, declining enrollment, and calls for accountability, Mackey’s work serves as a reminder that the real cost of weed-out classes extends far beyond failed exams. It is measured in lost potential, wasted tuition dollars, and the erosion of trust between students and the institutions meant to serve them. The question for universities—and the businesses that depend on their graduates—is whether they will continue to prioritize control over growth, or whether they will invest in models that nurture talent rather than weed it out.
