Acknowledge your fears. List any fears or concerns you have about going to college, then work through each of them on paper. For instance, if you are afraid you won't have adequate time to study, look at your current schedule and determine how you could structure your day to make study time possible.
Research financial options. If paying for college is an obstacle, speak with a college guidance counselor about financial aid. Ask about grants and loans, as well as scholarships available to older students returning to school. Consider whether you will need to quit your current job if you are employed and how you will support yourself and your family while in school.
Prepare for entrance exams. If you have concerns about being admitted to college, practice for college entrance exams. Tests such as the ACT or SAT have study guides and sample tests available. Enlist a tutor or ask the college guidance counselor about remedial courses if you need a refresher in some subjects.
Consider family matters. If you have small children, inquire if the college you are considering offers daycare. If you are not able to commit to attending all your classes on campus due to family needs, ask a guidance counselor about online courses you can take from home.
Speak to someone who's been in your shoes. Ask the guidance counselor to refer you to someone who has successfully completed college after 40. Discuss your concerns with this graduate and listen to solutions that worked for her before making the decision that is right for you.
