This is a set of three subjects: Constitutional Law, Civil Law, and Criminal Law. Immediate purchase is OK! Constitutional Law and Criminal Law are both 2021 editions, and Civil Law is a 2022 edition. There are some pencil markings (small circles, etc.), but they probably won't hinder your studies. All of them are very well-organized, and I myself used these to prepare for the short answer section, and I scored high marks (top 10%) on the actual bar exam's short answer section.
