W3 Schools HTML Quiz

I took the W3 Schools HTML quiz. I scored a 20 out of 25, which is an 80%. I took 4 minutes and 9 seconds to complete the quiz. I guessed on numerous questions, so the results aren't necessarily accurate to what I know. I got the questions about the correct HTML for making a drop-down list, a text area, inserting an image, <iframe>, and HTML comments. Those are things I still need to learn, along with inserting background images and colors.
