Hey @OshiKatsuFever,
Happy you’re here at CG Cookie!
To watch the Free lessons you do need to register for a free account. To watch the free lessons, on the course page there is a section called ‘Course Curriculum’ which lists the chapters and the lessons within each.
The free courses are marked as free on the course page and have a ‘Start Course’ button instead of a ‘Subscribe’ button, this may not be very noticeable to new comers browsing for the first time.
There is a welcome video in the pipeline to be added to the welcome page after a new member signs up.
You may want to also take a look at the Top 7 tips when starting to learn Blender article, towards the end I mention playlists, downloads and much more to find on the site.
Happy Blending!
