Which ACT score should I send for USC and UCLA?

October:
Composite-32(31.5)
English-32
Math-34
Reading-31
Science-29
Writing-36

April:
Composite-33(32.25)
English-30
Math-36
Reading-32
Science-35
Writing-31

In other words, how much will the writing score matter? Also, do subscores matter and will colleges take into account that I was one question away from a 34 if I send the April test?

For UCLA you need to send both (all scores if you have more!). Subscores matter. And they wouldn’t have time (or care!) to scrutinize you scores as much, to find out how many questions you were away from whatever score!
