Lex Omnibus does a great job distilling the overwhelming quantity of information in each OLQE Head into a structure that is much more manageable to grasp. With their help I was able to pass both OLQE Heads despite a Head I paper that focused on some unconventional issues (2020). The lecturers are very responsive to questions via email and have a genuine desire to help students understand the often difficult concepts. They also have a lot of experience marking the actual exams and this insight proved incredibly valuable.
