There are ways... but they're not guaranteed. Realistically speaking, it's up to the browser whether you can ever go "back". You can use redirect tricks or JS to encourage a browser to ditch its history... but if this is actually important then you'd better do it server-side: keep track of which pages they've completed, and ignore (silently (or noisily if you prefer)) any attempt to re-submit that section of the test. Now, I'm assuming that you really only care about preventing users from going back to change their answers - if you'd rather they not even be able to view their previous questions/answers, then you should be able to use cache control hints to encourage the browser to discard previous pages - when completed sections are requested, just redirect to the first incomplete section (or, a screaming red "cheater" page, whichever). Of course, there's no guarantee that browsers will respect this, but then, there's nothing preventing users from copying or printing previous pages either...

It appears that everybody is under the impression that I approve of the documentation. You probably also blame Ken Burns for supporting slavery.
