I currently attend CSUS as a junior
How many credits you have? That’s important since some colleges only accept a few after the required credits like 56
SDSU gives priority to local CC transfer applicants followed by in-state CC applicants so transferring with a high number of unit from another CSU will be tough unless you have an exceptional GPA. So what is your current GPA and how many units will have completed at time of application and a time of matriculation? How many upper division units will you have completed?
