To my understanding, "Secondary Schools" refer to High School or other forms of compulsory education. But the Secondary Schools section on the Common Information form has entries that pertain to degree-granting institutions. Either my understanding is incorrect or inaccurate, or the LSAC's online application is just poorly designed. I'm fairly sure which is more likely, but this is certainly an important and pivotal process -- one that I would like to complete with perfection. And that means zero mistakes.
