@lifeisastruggle It’s pretty easy - really just filling out some paperwork. During freshman orientation, you go to an advising session for whichever major you intend to declare. Basically, you just sit down with a professor in your department for 15 minutes and make sure you are scheduling the right classes for whichever major you want to do. As long as you take the right classes for the first year or two, declaring your major is just a formality. They don’t really reject people… I guess you could be asked to complete a class or two before being allowed to declare (in the case that something went wrong with your class scheduling fresh/soph year), but this would only happen if you were switching majors or something.
