CALI Lessons are online tutorials that have questions to test your knowledge of a particular subject and one of the topics is Contracts. We had you sign up for CALI access during orientation but if you missed that session or lost the DePaul code, please visit the Research desk in the law library with your law school id to receive another card.
Cali.org - lessons - 1L - Contracts - will show you the following: overview and sources of contract law, mutual assent, express and implied contracts and many more.
