It did not: https://pages.github.berkeley.edu/OPA/our-berkeley/enroll-hi... During this period, the undergraduate student population grew about 20%.

I was at Berkeley during most of this period. The undergraduate population swelled at the same time that the university was dealing with difficult budget cuts. The growth was significant enough that many students had, and still have, difficulty signing up for the courses they needed.

(I believe the cuts and the student population increase were related: admitting more students, especially out of state students, brought in more revenue. But there could have been other factors, like more students wanting a college degree after the financial crisis.)

To color this even further, at UC Berkeley I had intro courses with 1,200 students.
