Howdy Juri,
When you create an event in our plugin it will add it the calendar. One of the possible ways to view events is by month, as seen here. So in your case if each event were a class, they would each show up on the calendar just like that. Clicking on one takes you to the event/class.
With our WooTickets plugin you can add tickets to each event/class. In this case it sounds like you would want just one “ticket”, basically the sign up fee for enrolling. You can add that as a ticket. When a user visits the event page as described in the first paragraph, ad the bottom they will see an “Add to Cart” button. If they click that the event will not be in WooCommerce’ shipping cart, and is really handled by WooCommerce at that point. You can edit the “Product” as outlined by Simple Credits tutorial, and assign it to the “Credits” category. Since this is an ordinary WooCommerce product you should be able to assign it a Credits value as well. Based on Simple Credits descriptions, it seems like the two plugins should be quite compatible.
Does that all make sense? Did that answer your questions? Please let me know. Cheers!
