You should strive to find students, regardless of their ages, who can become a support network for you. Campus learning centers offer free help for undergraduates. They tend to focus on the areas of math, writing, reading, and study skills, and the many classes undergrads must take and find problematic. Regular users of Learning Centers experience higher grades than comparable non-users. Don't overlook campus daycare opportunities, counseling services, women's centers, and so on.
Many campuses have official non-traditional student support groups.
Shop around for some support. Resist the urge to keep your distance from campus opportunities. I made A's. Flash cards don't seem to be working now that I'm in college, though. I'm beginning to think flash cards aren't the answer.
