Exactly what your T&Cs should be will vary from site-to-site, but if you're not sure where to start then you're able to use the terms from our CEO, Greg's, site as a starting point.
Check that out here: http://www.alphascore.com/terms-of-use/
I set the terms and conditions. When I go to purchase the course there is a box that must be checked to agree to the terms but the terms are not there for me to review. How can the student see them before they check the box?
I checked out your site and a link to the T&C's is there. It just blends in a little right now because the link text is the same colour as the other text for your site (see below)
The link text colour is based on the branding colour set for your site (from the Branding page of your admin dashboard). So you can go there to change it if you'd like to.
Happy to help if you have any further questions at all.
