Not difficult. As long as you pass the exam in your senior year and reach 75%, you can be promoted, and then conduct a series of inspections and inspections. If there is a make-up exam, you are basically finished, because if you make-up exam last semester, then you will lose the opportunity to promote others next semester. After promotion, if you make up the exam or your grades are not up to standard, you can't become a key development target. It's best not to make-up exams for preparing party member, and don't have any major violations of discipline, otherwise the chance of becoming a full member is very low. But don't worry, when it comes to preparing for party member, everything will be easy, because the preparation period is one year, and it will be extended by another year, so if there is a local party organization, it only takes two years to become a full member. However, if the mass base is not good, it can only stay in the promotion stage forever, because the evaluation of classmates is very important.
