http://www.assist.org will show you course equivalencies for transferring courses from California community colleges to UCs and CSUs.
For other colleges, be sure to keep the syllabus and other course materials for evaluation of transfer credit and advanced placement should you enroll in such a college.
For applying to colleges, you need to self report and/or send transcripts for all courses at all high schools and colleges attended, whether or not your high school includes them on its transcript.
A calculus course suitable for math, physics, and engineering majors will be more applicable to more situations than a calculus course for business majors.
