I applied as a history major, what’s all this talk about being accepte to the college of choice, then picking a major? My major application asked my specific major.
If you are admitted to L&S, you need to complete the remaining prerequisites for your major and then declare as soon as possible. You must declare by the semester you will reach 90 units (including in-progress units).

As a practical matter, most transfer students enter with prerequisites that are only suitable for a few possible majors that they can declare in the first semester or two.
