<p>Okay so I've taken the SAT twice already the first score was 1540 my second was 1580 I feel like taking it again wont improve my score much. I want to attend UCSD and I know they recommend taking subject test related to your field in my case Biology , taking the bio subject test is recommended because it is an impacted major. The last scores they accept are the ones from the December test. I am trying to decide whether to retake the SAT one last time or take the subject test. I know this is a huge part of my application I also have a 4.3 weighted GPA and various extracurricular activities that I've done throughout my four years of high school.</p>
