Like any four year, the majority of your major courses have to be taken at the 4 year. They prefer transfers do the GEs and prerequisites (which may include some of the entry level major courses) at JC. S some major course may be accepted depending on major and courses, so there is no “one size fits all” answer. I would not count on petitioning to have a major course approved, it’s not in their interest to do so. Generally speaking, they either take it or they don’t. Again, not set in stone across the board, but they are gonna be a lot less accepting of a course within the major than a prereq.
