Do you know what a MOOC is? It may sound funny, but it can be a seriously valuable resource for you. MOOC stands for massive open online course. Basically, these are free or inexpensive online courses available to anyone—and they are being offered with increasing frequency by many big-name schools, including Harvard and MIT. You don’t get college credit for the courses, but it’s a good way to learn new skills or information, and may also be a way for you to do a trial run if you are considering going back to school as a paying student.
