"Degree conferral date" vs. End Date of courses for AMCAS / AACOMAS

Hi there!

My degree was awarded almost 2 years after I finished courses at my main 4-year institution because I needed one last class that I delayed taking at the local community college. The last quarter of classes I took at my degree-granting institution was Spring 2013, while my degree was awarded Spring 2015. When entering schools attended, do I put Spring 2015 as the End Date for my 4-year school? Or should it just be the end date of my last quarter attended there?

Thanks!
