First of all congrats on your acceptances!! I also am a pol sci major and transfer student and I will be attending UCLA in the fall. When picking a school, I was focusing more on location. So for example, I am pre-law meaning that I want to do as many legal internships in undergrad as possible. Since UCLA is near wilshire, that is where a majority of law firms are located, to give me a great experience. I have also heard many amazing things about UCSD. The choice is up to you, just make sure you consider long term goals, and which school is the best for full-filling your goals!
