How hard is it to switch into capped majors?
Specifically all Math majors, also Chemical Engineering?
I heard that switching into Computer Science is extremely difficult but how about other majors such as Math?
There is no guarantee that if you complete all the screening courses with excellent grades that you will be able to switch majors since it will depend upon how many spots are available at the time of your application due to attrition. You might want to contact the Department directly and ask how many students they do the accept each year.
I personally advocate that if you have a direct admit into your preferred major you should consider attending that school.
What are your other options and what major were you accepted into UCSD?
