Brackeys is known as one of the most popular Unity3D tutorial channels on YouTube; and perhaps even the internet. These tutorials will start from the beginning and teach you the basics, from the Unity UI, to scripting, all while helping you work step by step on playable, fun, and engaging game.

If C# isn't your strongest language, or if you've never been exposed to it at all, this complete beginner tutorial focuses a bit more on the programming side of Unity, including the use of the UnityEngine C# library. Don't be intimidated by the fact that the tutorial uses MonoDevelop - using Visual Studio will give the same results, and will even prove to be easier with it's out-of-the-box intellisense (code-completion aid).

As described by one of our club's founders, tutorials by Jason Weimann are perfect "if you want a quick and dirty overview of Unity" - Roselynn Conrady. This tutorial touches on both the Untiy UI, as well as some scripting, so if you are familiar with C#, (or Java, even), the pace of this video might be great for you.

Once familiar with Unity, these tutorials are a great introduction to Virtual Reality development. Also included is a tutorial on developing Virtual Reality applications without a headset.

catlikecoding.com is an incredibly huge text-based resource, including amazing tutorials ranging from mathematical concepts and algorithms, all the way to tower defense walkthroughs and map creations.

Yes, even the creaters of the software itself created some useful documentation... although it may not be as beginner friendly as Brackeys or similar, it can be a dense resource for those niche topics that peak your interest, like audio, animation, multiplayer and networking, and virtual reality.
