For a number of years, I have served on an Advisory Board for the University of Washington SQL Server Certificate Programs. Last year, UW took the program to the web for learning SQL Server virtually anywhere in the world. And you get to have Buck Woody as an instructor for one of the courses.
The course will meet virtually every week and there are assignments to be done. Often people find that this format for learning a subject works well because of the constant contact and expectations that are set at the beginning as you commit to taking the course.
