ACT Writing scores-to submit or not to submit?

Do UC schools require applicants to submit ACT writing scores? I’m asking because I recently took the ACT and got a below average score…will this hurt my chances of getting in at all?

The UCs require the essay parts of the SAT and ACT. Moreover, when ordering tests sent from the testing agency you cannot possibly exclude any section of the test from being sent.

You say you have a weak score but not what it is. The average score is about 6 so if you are at or above that, you probably do not have anything to worry about as long as other section scores are good.

My composite score was a 29, while my writing was a 5. I am retaking the test in June
