Applying for a major involves many aspects. First of all, I like science, but I should apply for science and engineering. However, we should pay attention to the low employment rate of undergraduates majoring in biology (bioengineering and biotechnology), so we should be cautious unless we want to get a doctorate. In chemistry, the employment rate of chemical engineering and technology is ok. Mathematics (such as applied mathematics), unless you teach it, don't take the exam.

In addition to these, there are many science and engineering majors, such as electrical engineering, mechanical engineering, electronic technology, software engineering and so on. The employment rate is good If you are an undergraduate, you should choose engineering, which is better for employment. You can choose a science major if you want to further your studies.
