Electives are the easiest way to go. But you may wish to look at the possibility of a minor. Those classes usually can get wrapped up into your degree. But whatever you do - be they electives or one-off classes...check with your financial aid office to see if they are covered. Not all classes on the side are. I don't like surprises...don't know many folks who do.
Whatever direction you go...and please take with a grain of salt...when you start college...don't stop. I took a semester off and...it lasted 9 years. I left because I didn't know "what I wanted to do". I was married to the idea that my college degree was going to define my future career. It wasn't until after that someone from the school told me - and here's the grain of salt bit...you go to college to learn how to learn, not to learn a career. (full-disclosure...trade schools are a different lot...but worthy and valid.)
Just...be strong going in...and get that degree...you got this!
I also shared this question when I first started pursuing my college degree! When first setting up my degree plan I figured there would be a stringent protocol for exactly what I needed to take. This was not the case. What you will find is there will be plenty of freedom for you in choosing classes that interest you. I found out that not only can you take classes outside your major and minor, but you should! College is truly a unique opportunity to interact with and learn from a plethora of subject matter experts on your quest to make the most out of your learning experiences. For most degrees you will be required to take a number of "elective" courses which will allow you to find a subject that best suits your current and future plans.
Best of luck in all of your endeavors!
I am echoing many others' sentiments but yes - you absolutely can take classes outside of your major while in college! There are many opportunities for electives. I agree that you should check with the financial aid office and your academic advisor to make sure these additional classes would not impede your graduation or major courses, but most colleges you generally have that additional freedom.
Also, if you would prefer to not be in journalism classes, some universities have open organizations like newspapers or clubs that are open to all majors. You may just need to apply to them, but it would provide you an outlet at college to work on journalism but not have to overexert yourself adding more classes to your schedule.
I hope this helps!
It is best to keep the course selected help you towards the end plan. Advisors/councilors in the college will be able to guide you further. You will have plenty of time to learn all these after you enter the college as the first two semesters are focused on the core curriculum.
