Do I have to submit all my college transcripts when applying to transfer?

Hello,
I went to the University of the Pacific (Private school in Stockton, CA) for my first year of college and now I attend a community college because it’s more financially beneficial for me. I plan to apply to a few CSUs and UCs, do I have to submit my UOP transcript along with my Community college one? I prefer not to because my GPA wasn’t great at UOP and it would drop my overall GPA.
Thank you!

Yes, you need to submit all your transcripts.

There is a College Clearinghouse that would have a record of all colleges you have attended, so yes all transcripts need to be submitted.

Duh.

YES! Unless of course you don’t want to get into ANY college.

Lots of us have some hideous grades in our pasts. But we still have to send all the transcripts. Generally speaking, good recent grades count for more than old bad grades at admissions time.
