To try it out for FREE, simply click the red button, fill out the account setup form and complete the payment form.
A credit card is required to start the free trial, but there is NO CHARGE to the credit card for the first 7 days. After 7 days, you will be automatically enrolled in the monthly subscription for $24.99 a month.
If you're happy with the subscription, no need to do anything, just keep on learning!
But if you feel it's not for you, you can cancel anytime. Just go to your student account, navigate to the billing page, and click the Cancel button. Easy peasy!
