Rails3: What REST URLs for the different pages of a multi-pages wizard?

I am new to Rails and its all-REST concept.

I am writing an exam website with Rails3.

During an examination, a user has to answer questions that are spread over 4 pages (kind of like a wizard).

How does this translate in REST?

I will probably have an Examination model with an /examinations/new URL, but I开发者_JAVA技巧 need 4 URLs for each of the 4 pages, how to achieve this in Rails3?

Odds are this http://railscasts.com/episodes/217-multistep-forms will answer your question.
