Sending SAT Scores To CSUs

I’ll be applying to CSU’s next month and I was wondering if I should send all my SAT scores or just my highest one. I’m not sure if they require applicants to send all of them but I got a really bad score the first time so I’m worried it might harm my chances of admission. Also, I’m taking it again in October and if I send all my scores now, will the college board automatically send my October scores or do I have to manually send those after I get the scores back?

Sorry if this was confusing. Thanks!

CSU’s superscore so sending all will not hurt since they will take the highest Math and CR score.
You will need to send the Oct scores unless you designate the scores to be sent automatically before you get the results back using the 4 free SAT reports.
