I just transferred from a community college to a 4 year and after being here for more than half the semester I’ve realized I’ve made a big mistake and want to transfer to SDSU. Can I transfer again? Will I have to start my upper division classes again?
IF the courses are comparable, then the credits and the grades should be transferable from one CSU to another; however, it would be up to SDSU to decide. Have you checked with SDSU? Beware that the timing as to when the courses are offered at these schools might not be synchronized, thus some scheduling issues might arise for you at SDSU. Continue to do your best at your current school and at SDSU; good luck.
I did exactly what you did when I transferred from Chico State to CPP. Apply, and see what happens. SDSU in general is a hard school to get into, and especially if your not a local. But then again, nothing is impossible. Good luck! Also, I think you might have to, but talk to them, and explain the situation.
