Student Material and Payment

Hello, I can’t seem to find the study material option on the student dashboard neither can I find it in the academics option. Do I need to purchase the pro version of this plugin before I can get the option??

Also I can’t seem to create free type.
I’d really like to know if I need to purchase the pro version, so I can know what to tell my client.

Also, is there a way I can restrict students who haven’t paid from viewing subjects in their class?
