I study materials science and engineering. Mechanical drawing is necessary, but it is not as difficult as you think. All mechanical drawings are drawn according to national standards. As long as you master the prescribed painting method, you can have a certain spatial imagination. Just study for one semester and get in. If you graduate from material science, you usually work at the grass-roots level of an enterprise in a high-temperature large-scale instrument and equipment environment. If you take the postgraduate entrance examination, you may go to scientific research institutes or enterprises for inspection. Going abroad has little to do with what major you study, mainly depending on whether you go to a university like 985 or not, and the tutors who follow the postgraduate entrance examination. With a good school and a good tutor, it is easy to go abroad. I am a girl, too. From the perspective of employment, it is more difficult for girls to read materials than boys. I don't recommend you to study this major.
