What is your UC GPA? And is your GPA of a 3.7 on a 4.0 or 5.0 scale?
UCSB will be a big reach for you. As for UCD, I believe it will be a reach. An SAT score of a 1200 is simply lower than both of the schools’ average SAT scores and 25% rank scores. What are you getting on your practice tests? Perhaps get your October SAT to a 1370 for better chances.
Good luck.
