<p>Admission to the Chemical Engineering major is determined by a number of factors, including an overall UCSB grade point average of 3.0 or better, and satisfactory completion of the following courses or their equivalents: Mathematics 3A-B-C; Chemistry 1A-AL, 1B-BL, 1C-CL, or their 2 series equivalents; Engineering 3; Physics 1-2. Decisions involving factors beyond scores and grades are made exclusively by the chemical engineering faculty. Only a limited number of petitions will be approved.</p>
<p>So I applied to college of arts and sciences under the major Economics and am probably going to be a freshman at ucsb this fall. I want to switch to chemical engineering. How hard would this be to do given the guidelines i pasted above?</p>
