DocMerit is a great platform to get and share study resources, especially the resource contributed by past students.
Northwestern University
I find DocMerit to be authentic, easy to use and a community with quality notes and study tips. Now is my chance to help others.
University Of Arizona
One of the most useful resource available is 24/7 access to study guides and notes. It helped me a lot to clear my final semester exams.
Devry University
DocMerit is super useful, because you study and make money at the same time! You even benefit from summaries made a couple of years ago.
