The first degree is the first full-time degree after graduating from high school. If you study undergraduate mathematics after the college entrance examination, then the first degree is the mathematics major of a university.

Except for the first degree, whether full-time or not, it will be called the second degree. Other continuing education, such as adult college entrance examination and self-taught examination, will be regarded as the second degree. In academic qualifications, there is another concept that is the highest academic qualification, that is to say, if a person graduated from a master's degree, then a master's degree is the highest academic qualification. There is no conflict between the highest education and the first education. The highest education may be the same as or higher than the first education.

A second degree is necessary.

The second degree has its rationality. Modern society is a rapidly developing society, and knowledge is updated more and more frequently, which is very necessary for the continuing education of cadres. However, in general higher education, it is unrealistic to ask everyone to leave their jobs completely for a long time, which is limited by time, economy, family and other factors.

Therefore, cadres should be allowed to study by themselves and take part-time jobs. However, one of the purposes of study is to obtain a diploma that can be recognized by the society and the country-the recognition of this qualification, so as to prove one's level improvement and competence for a certain job. The second academic education should be standardized and its credibility should be improved.
