Seriously, He is right.
my wife taught herself , html , css, php, java,
she is even good at SEO. All done online, you can go to places like
webmaster-world and they will help you on the forums.
I think downloading some e-books is better than online tutorials for a beginner. You can get a beginner book, then a more advanced one and then use the web to solve any questions that you might have A course is only worth it if the instructor is a really really good one or if you need somebody to force you to study
