Were you able to change your major after being accepted with your alternate major? (SJSU)

My acceptance letter says I have been admitted, but admitted to the alternate major listed on my application. Changes of major can’t be done until after enrollment into the school. Does anyone know the likeliness of being able to change my major after enrolling?

My original major: Kinesiology
Alternate major: Child and Adolescent Developement
GPA: 2.69
In-State (non-local)
