What Electives to Choose

Nowadays, colleges offer a great variety of electives for the students to choose from. Take Beijing Normal University as an example, the past 5 years has witnessed a sharp increase in the number of selective courses from 4 to 129, covering nearly every aspect of culture, science and technology.

When it comes to the choice of what specific electives to take, different students hold different opinions. Some choose practical courses to obtain necessary skills, so that they can have stronger competence in the future job hunting. While others select courses of their pure interest or courses that may look easier to pass the examination so as to get enough credits for the degree.
