LSAC
As you may already be aware, LSAC develops and administers the LSAT and offers online courses for sale on its website. Additionally, they provide a free online course with lectures on different LSAT question types. Be aware that this is a thorough online course, similar to others, and that it covers the most fundamental topics.
Having said that, the free practice materials you receive are the main benefit of taking this course. Before studying the fundamentals of the exam with the aid of exam preparation materials and video lectures, LSAC learners will take an entrance exam to ascertain their present level. There are two free official LSAT prep exams that are the full length, as well as one free official LSAT-Flex sample test. These, together with the previous practice material on this list should make up for adequate practice material.
