A method of limiting tokens for use by a student within an education application displays numerous membership options. For a price, a certain number of tokens are allowed per month. At the end of each month, tokens do not roll over; the account is reset with the monthly allotment of tokens. If the number of tokens in the account reaches zero, access is blocked. A method limits account sharing by using a limited time viewing window for videos and documents. A stated time limit displayed to the student is greater than the length of the video. An actual time limit not displayed to the student is greater than the stated time limit. Requests to restart the video within the actual time limit are granted. A request to restart the video after the actual time limit is denied unless the student again pays the number of tokens equal to the value of the video.
