Al Gore has posted 2.5 hours of free Revit tutorials for beginners over at:

He provides these starter files:

 and describes how to navigate and manipulate the model starting from here.

The videos include more advanced topics as your proceed through the series, including items related to documentation (not just modelling).

According to Al, over they years they have:
“put together a strategy, from many different sources, on how to draft in Revit. Now we have created a system to teach people that strategy. Through teaching hundreds of students and many professional we understand their sticking points, where they go wrong, and what they struggle with. So for the beginner in Revit I am very happy with what we have put together and think it will be of great value.”

Have you ever wanted a very simple explanation of what Revit actually is and what it does?  Sometimes it can be hard to encapsulate this for new users.  Perhaps this post will be of assistance:
what-is-revit – Revit

It includes step by step advice on learning Revit, plus links to resources (both online and downloadable).

If you have used Revit for a while, you may find yourself disagreeing with some of the advice – but hey, we all have different ways of getting the job done!

I leave you with this little excerpt from the post, wise in its simplicity:
