Page navigation now in Google forms

When creating Google forms you can now use a simpler page navigation feature to direct respondents to relevant pages regardless of their answers.

In the Google Docs list, select ‘Create new’ then ‘Form’ to create a new form. For multiple choice questions, you now have a new option to ‘Go to page based on answer’. If you select this, when creating the actual multiple choice questions, you have the option to navigate to a different page/item for each individual question.
