Hi all, I’ve been accepted to the UCSB L&S Honors program for Political Science, and I was wondering how hard it would be to switch majors to Economics? Thanks!
You can change to Pre-Econ but still have to take the screening courses before you are allowed to declare the major:
To enter the Economics major at UCSB, students must attain a 2.85 GPA or better in three courses: Economics 1, 2, and 10A. To enter the Economics and Accounting major, students must attain a 2.85 GPA or better in five courses: Economics 1, 2, 3A, 3B, and 10A. In calculating this pre-major GPA, the Economics Department only counts the grades from courses taken at a University of California campus. A student who has completed all courses except Economics 10A at a non UC college or university must earn a B or better in Economics 10A at UCSB. All other pre-major policies apply.
For students who have not met the pre-major GPA requirement, the Department is offering another avenue for admittance to the major. This avenue is open to students who have completed Economics 10A once and receive a grade of C or better. Students cannot have taken the course any other time, even if an “NP” was received in the first attempt. Students meeting these criteria will have two additional opportunities to take a comprehensive exam on the material in Economics 10A.
The first opportunity for the re-take exam is in the beginning of the quarter immediately following the quarter Economics 10A was initially completed, and the second opportunity is the final exam for Economics 10A at the conclusion of the next quarter. Students may take one or both of these exams.
The grade on the exam will only be used to give students an additional opportunity to get into the major. A student’s grade in either of those exams will be used to replace the grade they earned in the first completion of Economics 10A for the purpose of calculating their pre-major GPA.
The grade in those two exams will not change the original letter grade earned in Economics 10A.
If students do not take either of these additional exams in the quarter immediately following the completion of Econ 10A, no other options or exams will be offered.
Oh wow, thanks for all the info 
It is very easy to change majors within the College of L&S. Go to Cheadle Hall http://duels.ucsb.edu/advising or talk to your honors adviser.
To switch into any major really you just need decent grades in the pre major courses. I am a second year working on econ pre major courses to switch in. You dont need to be pre-econ but it’ll make enrolling in the classes you need during registration times easier. As long as you receive good grades in any pre major courses really it’s pretty easy to switch. Switching into something like engineering is really competitive but possible. Same with econ because of the curves they use in pre major classes to weed people out. I recommend meeting with an advisor and switching into pre-econ soon so signing up for classes goes smooth
