Moodle in English

I can't believe this is not a default setting.

I don't want Adaptive mode on because I want the student to no be able to change their answers, once they know the correct answer. If I turn it off I lose the Submit button and the only way to advance to the subsequent question is to click the Next link.

Clicking "Next" is not the intuitive response. Clicking "Submit" and having the screen advance to the next question has been standard behavior for years.

The Submit Button code beginning at line 505 creates a button for the adaptive mode as follows:

echo "<input type=\"submit\" name=\"markall\" value=\"".get_string("markall", "quiz")."\" />\n";

What values passed to get_string would result in the button posting the answer and moving to the next question?

Thanks.
