Not necessarily true, if your career goal is not one that requires graduate or professional school. For example, if you want to work as a civil engineer, earning a bachelor’s degree in an ABET accredited civil engineering program makes more sense than earning a bachelor’s degree at a school that does not offer such a major.
Most college students going to work after their bachelor’s degrees need not freak out about grades as long as their GPAs start with a 3 (or 4) on a 4.0 scale (some “elite” employers may be exceptions). But those who want to go on to graduate or professional school may have to focus on their GPAs if such graduate or professional programs are highly selective.
