Education at a university level is something that many seniors decide is an important investment for their lives. However, it is difficult for many of them to afford these classes, especially if they are simply interested in education, not job training. Thankfully, free and reduced-cost college courses are available for seniors across the nation. These courses are offered by accredited universities and are a great way for seniors to attend the university of their dreams or even achieve a bachelor, master, or doctorate degree. Understanding these courses requires understanding why they are offered, how seniors can attend these courses, and any limitations on their course work. For example, some universities may waive fees for courses that don't provide college credit. These limitations are important to know before diving head-first into the world of higher education for seniors.
