UC Berkely is a very rigorous college to get into. They're going to want top SAT scores 1500-1600 and They have most selective acceptance rates and have trends of accepting less than 10% of applicants - yikes! But don't get discouraged! If you work hard and begin the college process with a very intential mindset you can set yourself up for success early on. Get good grades, participate in extra curriculars, volunteer, prepare for the SAT often and early (to ensure your scores will be high) and you will be on the right track! Collegeboard.org is also a great resource for this! I poured through the pages of universities all over the U.S. when I was a senior in high school. Collegeboard was my go-to site! They put all of the information in one place and it is very easy to use. They even have various filters you can apply to see only colleges that have programs you are interested. To determine academic rigor, look at the admissions requirements, G.P.A. of past admitted applicants, SAT/ACT scores, class rank etc. This will give you an idea of what scores and grades you need to be accepted. However, don't be discouraged your application will be reviewed based on the full picture! College-board will help you get an idea of what is most important to the specific school you are applying to.
