In Guangdong, because the 3+ certificate exam is simpler than the college entrance examination, and the qualifications obtained by entering the university through this exam are the same as those of ordinary high school students, many secondary vocational students choose to take the 3+ certificate exam to try their luck.

However, due to the poor foundation of secondary vocational school students, it is still difficult to lower the requirements of the 3+ certificate examination and reduce the difficulty, so many students choose to enroll in remedial classes to improve their academic performance. Because there are many remedial classes in the market, many students may not know how to choose.

When choosing training institutions, we must take a look at their teacher resources. There is a big difference between an experienced teacher and an inexperienced teacher. After all, teachers are the ones who have the most contact with each other. Moreover, the reputation of training institutions comes from teachers to a large extent, and teachers with rich teaching experience can easily solve many things.
