I also wonder how closely the UCSD math placement process actually correlates with standardized tests such as the SAT and ACT.
Do students above a certain cutoff level on SAT/ACT consistently do well on the UCSD math placement test? Or are students managing to get through high school math and even do adequately on SAT/ACT, but are missing fundamental middle school level math or elementary math skills, and this deficit is then exposed on the UCSD math placement test?
I did read through the entire report and I don’t know the answer to this.
