Alex Tabarrok summary:
Alarmingly, the instructors running the 2023-2024 Math 2 courses observed a marked change in the skill gaps compared to prior years. While Math 2 was designed in 2016 to remediate missing high school math knowledge, now most students had knowledge gaps that went back much further, to middle and even elementary school. To address the large number of underprepared students, the Mathematics Department redesigned Math 2 for Fall 2024 to focus entirely on elementary and middle school Common Core math subjects (grades 1-8), and introduced a new course, Math 3B, so as to cover missing high-school common core math subjects (Algebra I, Geometry, Algebra II or Math I, II, III; grades 9-11).
In Fall 2024, the numbers of students placing into Math 2 and 3B surged further, with over 900 students in the combined Math 2 and 3B population, representing an alarming 12.5% of the incoming first-year class (compared to under 1% of the first-year students testing into these courses prior to 2021)
(The figure gives some examples of remedial class material and the percentage of students getting the answers correct.)
The report attributes the decline to several factors: the pandemic, the elimination of standardized testing—which has forced UCSD to rely on increasingly inflated and therefore useless high school grades—and political pressure from state lawmakers to admit more “low-income students and students from underrepresented minority groups.”

“This deterioration coincided with the COVID-19 pandemic and its effects on education, the elimination of standardized testing, grade inflation, and the expansion of admissions from under-resourced high schools.”
