<p>At Berkeley, most freshmen engineering students apply to and are admitted directly to their engineering major. A few apply to and are admitted to engineering undeclared (which is different from undeclared in a non-engineering division). Engineering undeclared students have about a year to declare the engineering major of their choice; non-engineering students must apply to change into an engineering division (this is a very competitive admissions process). Declared engineering majors who want to change to another engineering major must apply to do so.</p>

<p>Math, statistics, computer science, biology, physics, astronomy, and geology are in the College of Letters and Science at Berkeley (where all applicants are admitted undeclared); these majors are not impacted and can be declared after completing the prerequisites. Gaining admission to the College of Letters and Science at Berkeley is still quite competitive, though.</p>
