Solutions at your fingertips

The Homework Library (HL) is a database of solved homework problems derived from the endless collaborations between our tutors and students. Every item in the HL is the result of one of our tutors helping to raise a student's understanding and skills to a level sufficient to produce the final product on display in the HL, a testament to the success of the academic partnership.

HL materials are not original and are therefore made available for the sole purpose of studying and learning. Misuse of HL materials is strictly forbidden.

The HL was created for students who need immediate help, and in many cases you can find step-by-step explanations on how to solve a problem or examples of proper writing, including the use of citations, references, bibliographies, and formatting. If you don’t find what you are looking for within our HL database, please reach out to one of our tutors and schedule a tutoring session.
