I've just added a new tool to Road To Grammar. Now you can create a multiple choice quiz, like the ones on Road To Grammar, and save it on Road To Grammar for your students (or whoever) to use.
The best thing is that there is no log-in necessary! But you can add a password if you like. When you finish creating and uploading the quiz, you will get a unique URL where the quiz will be located. Here is an example: http://www.roadtogrammar.com/myquizzes?11qh
Try it out, create your own quiz right here: http://www.roadtogrammar.com/myquizzes/qm.htm
