Vocational Choices
Vocational choices mean what kind of positions you want to take after graduation. Different people hold totally different attitudes towards vocational choices.
Some people want to take positions that are related to their majors, some not. Personally, I would prefer to work in an area that is closely related to my specialized knowledge. Why? Because applying what I have learned to practice gives me a sense of achievement.
There is no doubt that this sense of achievement could also be achieved through success in other areas, but in terms of vocational choices, a greater sense of achievement can be got in your own major. Whatever your view on vocational choices is, the first priority should be placed on comprehension of professional knowledge.
