I quite agree that on a page with a fairly large number of questions, in adaptive mode, when a student has clicked on the Sumbit button of one question, after the page has refreshed and is displaying the feedback for that question, the screen should jump back to that question, not to the beginning of the screen. This probably could be achieved with some Javascript. I'll try to look at it in the coming days... At the moment, the Moodle interface is still plagued with a lot of page refeshes, and I am looking forward to the promise of fewer page refreshes with the adoption of AJAX in future versions...
