Creative Cloud Student Discount

I believe the age requirement is 13 years.  If you don't understand the TERMS, ask a parent or teacher to help you.  

Subscription & Cancellation Terms:

The Student plan is a one-year committment.  If you cancel early, there is a 50% termination fee. 

The introductory price is appoximately 60% off ($20/month) for 1 year only, after that the discount drops to 40% ($30/month) until you cancel or leave school.
