"California Universities just had the most applications in history. UCLA 145k applicants, UCSD 130k applicants. Respectively they are both down now to about a 3% and 5% acceptance rate due to the spike. Might be Covid holdovers due to a gap year, or with the economy as it is, out of state applications have dropped."

If it's true, that's crazy. Up until this year, I think the lowest acceptance rate was Princeton at 3.9%.
