Getting an internship in your field may help you realize what you like and dislike about the field. These jobs will also help you realize what you want out of a job and career after college. Build strong relationships with your instructors. Building rapport with the professor makes it easier to come back and ask for letters of recommendation and other favors you will need later on in your collegiate career. Approaching your professor may be difficult at first.
Professors can be very intimidating.
After all, these are people that have dedicated years, even several decades, of their lives to studying their one subject. Some of your professors may even be internationally renowned Nobel laureates in their respective fields. As a student, however, it is you who must take the initiative and establish the relationships with your professors. If you thought that the pressure to perform extracurricular activities ends with high school graduation, guess again. Doing volunteer work outside of the class is an excellent way to show future employers and graduate schools that you are truly committed to your chosen field of study.
