First, we need to focus in order to make a good decision on what course or career choice. In your case, I realize that you are hesitating between two courses. In this case, you can write on a sheet of paper, the points that attract you in each course. The course which has more positive factors can be chosen by you:
Consider your passions, interests, and values.
Think of your favorite subjects and classes in high school.
Consider job prospects.
Read the course catalog at your college or university. 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.
Consider your school's reputation. 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.
