Subscription site with several free tutorials
Ranked in these QuestionsQuestion Ranking
Pro Very complete
Blender Cookie has long become CG Cookie. The site includes whole courses of study that are divided along professional lines. For instance, texturing and game asset creation, rather than making plants or vehicles.
Pro More than Blender
For the price of subscription, you access to all the courses on CG Cookie. That includes courses on Unity, game building, concept art, and physical sculpting. If your interest in Blender is part of a larger interest- making statues or figurines, making movies, building video games, etc., then CG Cookie is the site for you.
Pro Lots of great free content
CG Cookie was revamped a few years ago to better suit building a set of general, professional skills. The old content, which was more like the typical "how do I make a living room" or "how do I build a figure," is all available for free in the archive. It includes all their tutorials from 2008 to 2015, and they're some of the easiest to follow and most informative tutorials for Blender out there.
Con Generalized content
CG Cookie is great if you want to learn how to do something in general, like texture or model. It's now less good if what you want to learn is specific, like how to make really good grass or cars.
Con More for beginners in the areas they cover
If you already have a very complete skillset and just want to fill in specific gaps of knowledge, CG Cookie isn't the best site for you. It's great if you want to add an entirely new skill to your repertoire, or learn a new tool or technique (they cover Zbrush, 3DS Max, and even lost wax casting). It's not so great if you want to get better at making clothing details, or improve your anatomy skills.
