Barnet and Southgate College will raise awareness about Adult Learners Week at shopping centres and libraries.
Students will celebrate the annual event by urging more people to take up learning a new subject later in life.
It runs from June 16 to 20 and the college, in Wood Street, High Barnet, will hold a series of workshops.
Former student Sema Ucunu, 43, moved to London from Turkey in 1997 and found a job as an administrator, before getting married and having a son.
But after becoming a single parent, she decided to study childcare after volunteering with Brookhill Nursery, in East Barnet, where her son attends.
She said: “Being a mature has helped me focus on my studies. It is a good feeling being older than most other students.
“I feel so happy when I am going to College to meet and chat with everyone – I have made so many friends and it keeps me young.
“It is a good feeling being older than most other students. I feel so happy.”
