-I am applying to transfer out of a CSU as an Econ major for Fall 2016.
-GPA:3.5 (I have 3 quarters left to improve it)
-I’ve heard that it is nearly impossible to
transfer to a UC out of a CSU, so I decided
not to apply to any UCs.
-Now as I am applying to CSUs, I am hearing
the same comments about the CSUs I want
to attend.
-Which schools are my best bets?
**Any suggestions/thoughts/advice/previous experience. Please share 
A 3.5 should be plenty to get you in most place. I’d suggest you TAG UCD or UCSB.
Only community college transfer students are eligible for TAG, aren’t they? @NCalRent
The problem with CSU’s is that many will give high priority to local CC transfers such as CSUN and SDSU especially.
CSU to UC is possible, just harder to make sure all your classes are transferable. You have a solid GPA, so I would consider some of the UC’s along with Cal States and apply broadly.
There is also a UC transfer thread that has very knowledgeable posters whom could help you with your questions regarding both UC and CSU transfers.

Good Luck.
