Preparatory class is a kind of training class for high school graduates to enter universities. The employment prospect is not directly related to the preparatory course itself, but depends on the professional and personal abilities of graduates. Nevertheless, preparatory classes are still helpful for students to improve and prepare for university study.

The employment prospect is influenced by many factors, including market demand, industry development trend, personal ability and professional knowledge. When choosing a major with good employment prospects, you can consider the following aspects:

1. Industry demand: When choosing a major with good employment prospects, you can pay attention to the current and future industry demand. For example, IT, finance, health care and other industries have been hot areas of employment in recent years.

2. Development trend: When choosing a major, you can pay attention to the development trend of related industries. For example, with the popularization of digitalization and Internet, the professional employment prospects related to computer technology, network security and data analysis will be very good.

3. Personal interests and abilities: Considering your own interests and abilities is also an important factor in choosing a major with good employment prospects. Choosing a field that you are good at and interested in can improve your learning motivation and work enthusiasm.

Generally speaking, preparatory classes provide students with opportunities to study in universities, but the employment prospects still depend on students' professional choices and personal abilities. The important role of preparatory classes is to provide students with certain knowledge reserves and academic preparation, so that they can better adapt to university study.
