Do I have a good shot at getting into a UC or maybe even an Ivy league?

well its kinda early to see where you can get in, you still have you junior year where you take a lot harder cles. Also, star test are a joke. Your score in the ACT or SAT will also be a factor. Anyways, you can automatically get into any UC, for the exception of Berkley and LA which are a reach for you though. As the the Ivy league, its too early to tell but it can also be in reach, just remember though to write a good essay and try to demonstrate how you are unique from other students. You need to stand out of the crowd.
