Hello, I am a current senior in highschool for fall 2016. I got a 1300 out of 1600 on the SAT in May. My dream school is UCLA. In October 2016, do you think I should take the SAT again to see if I can get a higher score? Or take SAT subject tests? (I would take biology and matematics level 1 and 2 because I would like to major in biomedical sciences) Thank you!!! 
SAT since average scores are in the 1400 range. SAT subject tests are recommended only for a few majors. If possible, take both to strengthen your application. UC’s accept up to the December sittings. Take Math 2 only not Math 1 and Bio.
