Want to know what is the difference between the 5-year college entrance examination and the 3-year simulated AB version? I am poor in mathematics in Fujian. Please analyze whether to buy a or b, thank you. A is to divide the knowledge into small chapters, which are more detailed, and B is a more systematic and comprehensive review, which tends to be comprehensive. It depends on your foundation. It's better to suggest B. It's not particularly good. A is recommended, which is really detailed and basic. If you want to make it hard, you will definitely surpass a large number of people in your school in math. After all, Fujian paper is also dominated by three books. Our school was 5.3 fierce in that year, and mathematics was particularly sharp! I believe you can, too!
