Do you have a natural talent/skill? Don’t discount any natural talents or skills, instead, let those skills guide you to success.
Possible careers? What sort of job will your degree prepare you for? Will you need additional schooling to achieve your career goals? Is your major geared toward one particular trade (for example; engineering or accounting) or can you apply it to many careers (Majors such as English, history, psychology that teach marketable, non-trade specific skills such as reasoning, critical thinking, writing and communication)?
What are the requirements? What courses and how many will you have to take within the major as well as supplementary courses outside your major (i.e. accounting students take courses in marketing, economics, and business as well as specific accounting courses). Does the program require a minimum GPA for admission and retention? Will you need a minor? Will you be required to complete an internship or a co-op program?
