The VTC Online University gives unlimited access to over 81,350 tutorial videos (more than 782 courses) in the library. You are billed according to your renewal selection - monthly $30, three months $90, six month $180, or yearly $250. For monthly subscription you will be billed every 30 days until you cancel. Our terms of service state that you must cancel a monthly subscription at least two business days before your renewal date. These two days give us enough time to ensure that you will not be charged again. Payment for single users is by credit card only, and will appear on your card statement in your local currency.
