After I am done with Information Technology classes at Rochester Institute of Technology for my concentration: web developer / programming. Then, I feel there's something I need more: learning new stuff related to web progamming which never existed what I learned at Information Technology class courses. I find the interesting site, which I can learn myself from tutorial site, you can learn: HTML, XHTML, CSS, SQL, XML, XSL, DTD, JavaScript, DHMTL, and list goes on.
I enjoyed learning SQL tutorial for my first time and I took quiz for that after learning all SQL. I got 65% (13 out of 20 questions) on my first quiz. I also tried HTML and CSS quizzes without looking their tutorials. I got 80% and 85%.
