I clicked on the "Go Bar" and typed in courses... and all these courses showed and looks like I have access to them. Never seen them before..
Are they free?
If I use them will FL charge me?
No, if you do not own them, you have access for a fixed period of time. In the library, check the license column on them to see if they are owned (permanent license) or trial (temporary license).
I assume you are looking at the Courses Tool - and seeing a number of courses listed there.
If you see them they are either Courses you have purchased or courses made available for free.
If they are there you can use them without any additional charge.
Thanks again.
