I went to a CA JC and then a state college, I have worked in the accounting profession with CAL, UCLA, UCD, USC, UCSB and Stanford grads for 30 years. It makes 0 difference if you went to a JC to get to those other schools. It makes 0 difference that you are a Stanford or San Francisco State grad. The school you attend is not a question asked on the CPA exam.
The business school JC prerequisite courses that transfer to a UC, such as Acct 1a, 1b, Econ 1a 1b, statistics etc. use the exact same books a and cover the same material. Both the CA JC, UCs and Stanford are accredited by the same organization. Sure you are more likely to run into students that aren't ready for Acct 1a at a JC then a 4 year school but the only thing that matters is how you as a student approach your class whether its at college of marin or UCB.
My son attended a JC. Several schools have been mentioned as not having JC transfers on their rosters, I can tell you those schools do recruit at JCs, they just didn't land the player. A JC player is far more knowledgeable about the programs doing the recruiting then a HS player and his parents. A JC player usually looking for an interested coach and a legit opportunity to play at a good school.
