It looks like you’re assuming (presuming?) that UCSD has more baccalaureate applications to med school/year. This isn’t so as in the 2018-19 academic year, UCLA had 1,014, Berkeley had 662, UCSD had 578. Florida had 852, which was closest to UCLA. I’m sure that the rate of acceptance for UCLA and Berkeley would be in the 50% range or a bit higher, but not 60%. And one has to remember that those who assent to release of data to the universities to display these data in surveys are probably looking for greater assistance. SD’s numbers are probably lower, which caused the administration there to start an inquiry as to why the numbers have dropped, but it may be because of my previous sentence.
I agree, though, that thegriz01 shouldn’t be afraid of the competition at UCLA. The students there are collaborative and competitive – as these two words are not mutually exclusive. And I’m sure that there are plenty of fraternal groups of UCLA grads who’ve become MDs.
