History
Study Notes began as a way for the founder to share his Advanced Placement notes with his classmates. But it grew to include the notes of his classmates as well, covering three courses: AP English, U.S. History, and U.S. Government. The tool currently supports seven AP courses.

In 2014, Study Notes began offering a database of sample college essays for prospective college applicants to use for inspiration during their essay writing.
