How to pay for school is a big factor when looking for a college. Fortunately, 
there are many scholarships out there for engineering students. The scholarships may have requirements such as certain GPA's or national test scores, financial need, academic majors or essays. There are also scholarships that are more general. It is a good idea to look into engineering scholarships even if you do not have a demonstrated financial need, as there are many scholarships that are not need based. In addition, many universities also offer scholarships specifically for their engineering students.
