Flubaroo is a free tool that helps you quickly grade multiple-choice or fill-in-blank assignments. I designed it for my own classroom, and want to share it with other teachers... for free! Flubaroo works with Google docs.

FormEmailer is a Google Apps Script for Google Forms and Spreadsheets. With it you're able to easily set up flexible e-mail merge in your spreadsheets and automatic emailing to your forms. The best part is that you need NO javascript knowledge, and everything is set up in a simple interface.
