Quizlet is open to students of all ages but there are several differences for students under 13 years old.
When you create an account and you are under 13, Quizlet will send the confirmation to your parent's email address and they will have to confirm your account.
Facebook, Twitter, and Adding friends
If you are under 13, we remove access to social sharing features like Facebook and Twitter.
Also, you cannot add Friends on Quizlet if you are under 13, but you can search for them by Quizlet username in the search box to find friends' study materials.
After your parent confirms your account via the emailed link, you can make your sets public. Until then, all sets will remain private.
If you are under 13, you can make and bookmark folders, but your folders cannot be bookmarked by other users.
If you are under 13, you can join a class but you cannot create your own class.
You cannot see or use discussion/chat boxes on the study set pages.
You cannot upload your own image for your profile picture if you are under 13.
