"This was the most awesome summer experience I've ever had. I totally recommend it to any college-bound student. You get the complete taste of college, the dorms, the classes, and even the activities! There are RAs(Resident Assistants) that are undergraduate students of the UC you choose to go who plan all sorts of activities for you in campus, so it is like really living in a college. The cost is not bad-- about $2000 (for CA residents) for 4 weeks, it's really inexpensive compared to most summer residential programs. This cost covers everything, including the weekend trips to adventure parks, zoos, kayaking, etc. (depends on the campus you choose to go to) The classes give you a totally hands-on experience that you would never get in regular high school. The instructors there help everyone out a lot. There are "clusters" of various topics of science, so if you're into science, it's somethign definitely took take a look at."
