I just joined the website and still have some doubts as to how it works. I understood that once you become a premium user, you can download 30 worksheets that have been recently published. However, is there any way we can have access to previous material? If so, how? Thanks for your help! I really appreciate your comments.

Best wishes,

Once you become a premium user you can use your credits (adding up from the number of times your worksheets have been downloaded by other users) to download past published worksheets.
