Any recommendations on when to register for SATs/ACTs? Due to the fact that UCs/CSUs aren't requiring scores, my school isn't offering insight on any testing this year. I'm a junior, and I need all the help I can get. As of right now, I´m considering registering at another testing site, but I'm not sure which schools in California are offering. I had checked the College Board website, and it listed my high school as one of the testing sites even though it isn't. I'm afraid to register for a testing site if everything's still up in the air.
