Google Forms are great for collecting survey and assessment data, but sometimes you may wish to turn them off when you have received a certain number of responses (e.g. if you are offering a PD class and only have room for 20 people, or you are organising a field trip and only have room for 40 students). Thankfully, there is a way to do this using Add-ons . Here's how: Step 1: From your form, go to the Add-ons menu and select Get add-ons : Step 2: In the window that appears, type in "Form Limiter" , hit Enter , and then click + Free on the blue button that appears: Step 3: Click Allow Step 4: Now, go to the Add-ons menu and you will see there is a new option called formLimiter . Select this menu, and then Set limit : Step 5: From the menu at the right-hand side, select the type of limit you wish to impose: Step 6: Set your limit and response message, then click Save and enable
