SMC and PCC is not a matter of transferring from say a Harvard to an NYU into a USC etc. With community college there is no advantage over another school in terms of transfer admissions for the UCs. As long as each school has transferable courses, and you fulfill the IGETC your chances at transferring from PCC and SMC are the same. It just so happens that there's probably a higher concentration of students at SMC who tend to aim for the UC's and USC more than other community colleges around the LA area. Therefore it looks like SMC has an advantage, when it's a matter of course offerings, and getting your classes fulfilled with the highest gpa you can achieve.
