Good Morning Syed,
Some school programs require an internship prior to graduation. Whether or not your school does, an internship is generally a great idea. It gives you the opportunity to gain experience in one setting, in a field for which you are studying. This "real world experience" helps to shape your understanding of your chosen field, the environment in which you work, how to interact with employees and management, and much more. Check with your teachers or instructors about how to find an internship. Many are available with part time hours to accommodate a school schedule.
