Every year, the school organization department gives the college training indicators, but freshmen may not be able to do it. The hard indicators that can become development goals are: excellent schools, graduation from group classes. After the party class training, there will be a party class exam, and you must pass the exam to have a chance to become a preparatory party member. The earliest party class is in the first half of sophomore year, that is, in winter. After passing the party class, the instructor will select a few qualified people to prepare party member.
By the time you graduate from senior year, the number of people who can join the party in a class should be around 4-5, and some classes are unqualified in hard indicators, maybe only 2-3. Moreover, the squad leader, the Communist Youth League Secretary and the study committee members are all given priority in joining the Party. As long as you don't fail, you can talk about anything.
