Most of the automatic full ride scholarships in older lists have been discontinued, reduced to smaller scholarships, and/or made competitive since then. Students with National Merit status may have some additional ones available, but those also have become less common.
Here are a few possible remaining ones that do not depend on National Merit status, but you should check with the school, since the wording on the web pages could be interpreted as either automatic or non-automatic. (Whether they use unweighted or weighted (and how weighted) HS GPA is another question to ask.)
