Google Forms is a simple, handy tool for creating quizzes and questionnaires. One thing that slightly bugs me with Google Forms, though, is that there are currently no tools available for formatting the text in the quizzes. This makes it a bit difficult to add, fox example, bits of code in the quiz questions and highlight them properly.

However, as this article at GAFE points out, you can use a handy Unicode text converter to convert strings of ASCII text to various styles created with Unicode characters. For bits of code, the converter produces a nice monospaced variant that you can simply copy-paste to Google Forms.
