Program Costs

BestColleges surveyed 2,663 Americans, and 60% of respondents said that cost is one of the most important factors when choosing a college. To determine the actual cost of college, consider not only tuition and financial aid, but also fees for books, supplies, and other amenities. Some majors may lead to more lucrative careers than others. For most students, the cost of a program versus return on investment is more important than a school's prestige.

Course Workload

Some majors require more coursework, additional exams, and higher expectations. It's essential to investigate course requirements before declaring a major to understand how rigorous your workload will be each week. For example, architecture and chemical engineering typically require more time each week than majors like criminal justice and public relations.

Income Potential and Employment Opportunities

College majors and minors offer students an opportunity to explore various career paths. Still, it's a good idea to consider earning potential before choosing a field of study. STEM careers are usually higher-paying than positions in human services, education, or the arts, for example. However, pursuing a career you're passionate about may outweigh the desire for a larger salary.
