The Level 1, Level 2, and Level 3 exams all have questions from the original official book (document [6]). These after-school questions were officially produced, and they were in line with the actual questions and language style. Doing these questions could help the examinees deepen their understanding of the knowledge points and understand the association's method of setting questions on these knowledge points. In addition, some training institutions also provided 100 questions for the first, second, and third levels of the CFA (documents [2] and [7]). These hundred questions were based on years of practice and analysis of the key and difficult points of the CFA exam, as well as predicting the key points of the exam. Doing these hundred questions could help the examinees familiarize themselves with the type of questions and the style of the questions, and improve the speed and accuracy of solving the questions. To sum up, if you want to find the post-class questions for Level 1, Level 2, and Level 3 of the CFA, you can choose the post-class questions in the official original book or the hundred questions provided by some training institutions. These questions could help candidates consolidate their knowledge points, improve their ability to solve problems, and better prepare for the CFA exam.
