You can try forming or joining study groups as it helps with maintaining a strict schedule since you not only study for yourself but also for the group members. In courses where I was part of a study group, I found that older students were ideal to have since they often were viewed as a parent and group members looked forward to working with them. I also found older adults sometimes use a different studying technique or way of thinking about a particular subject, especially if they can include personal experiences. It benefits the group so in turn, group members are more willing to go the extra distance and help the older student.
