Article in English: If you have already been accepted to a school, then read the course catalog to learn about the different majors, their requirements, and the types of courses involved. Remember that sometimes the titles of classes are misleading, so be sure to read some of the course descriptions for more details.  Be sure to read an up-to-date course catalog, as majors and their requirements change over time. Take into account the number of units you will need to take, the subject matter, and the work load. Does your school specialize in Journalism? Agriculture? Medicine? Engineering? If the quality of the education you receive is of utmost importance to you and you are still undecided between majors, then consider which departments or majors your school is most well-known for. Do some research on your college to learn about which departments are most reputable, and which professors are most esteemed and recognized in the academic community. Whether you are undecided between two or more majors, or have absolutely no idea what major to choose, then set up a meeting with a counselor at your college. If you haven't graduated yet, then set up a meeting with your high school counselor.
