Using Google Forms to Create Surveys

Google Form is a free tool that can be used to collect information, give quizzes, or perform online surveys.  In this tutorial, we are going to learn how to use Google Form in creating a simple survey. In this survey, we are going to ask for students who are interested to attend and Advanced Calculus Class to fill out the form. The only information needed are their full name and their course. The final output of this tutorial is this live form.
