My older daughter applied undeclared everywhere. She always leaned towards the social sciences, but she truly didn’t know what she wanted to major in and, she felt she needed to explore. We encouraged her to attend one of the less competitive UC campuses where she had been accepted. Having graduated last June within four years, I believe it was the right choice. Her merit scholarship came with priority registration, which allowed her to register in any course that she fancied in order to explore. When she suddenly wondered at the end of her sophomore year if she should switch to the college of natural sciences, she was able to register in a key chemistry course next fall quarter which would have allowed her to switch colleges and still graduate within four years. She took the course, and decided that she was definitely a social sciences student. She declared her major that quarter and never looked back. The point is that had she decided to pursue the natural sciences, she still could have; save probably for engineering, most other doors were still open to her at that point. She had acceptances at more selective universities, but I doubt she would have had the flexibility to explore and to change course if necessary.
