Last year, I signed up for a course of nitrogen guide education. Because I failed to apply for the exam last year, I took the exam for another year. So when I applied for courses, I repeatedly compared the application courses of several training institutions. Later, one of my senior sisters recommended nitrogen guide education, which was really good. The application is closely related to political topics and current events, forming a unique set of "fill-in-the-blank questions", and my grades have improved a lot. Finally, I applied for high marks.
