See which major is good, if math is not good, I suggest not taking math, or taking a three! I don't know if there is! It is relatively difficult to calculate one ~ If Twilight (contact TA in the station) is not good at math, it is recommended not to take the math test. Their school should also have other postgraduate courses with Beckham's love for football (TA in the contact station). I studied ecology. The Shenyang Institute of Applied Ecology, Chinese Academy of Sciences, which I took last year, is the only specialized course in mathematics. I didn't take the math exam because I didn't review well. (In fact, it is not very difficult, 8 choices, probably 10 big problem, high number+linearity. ) first, ecology is not difficult, even if it is cross-professional. Generally speaking, it is ecology+animals or plants or microorganisms, and it is generally reciting subjects. Second, ecological employment is very difficult. You have to think about this, which means that society does not need talents in this field now. Once you leave the research field, it will be more difficult to find a job, and the professional examination for civil servants will be more restricted. Third, recommend several directions, animal ecology is better than plant ecology; Application, such as ecological restoration, landscape ecology is superior to theory; Be careful when taking the ecology test in Beijing Normal University. The second interview card is very strict, and good schools don't fool you. Fourth, the ecological potential is great, but it may take 10 years or even longer, depending on whether you can bear it yourself. Classmate, any kind of ecology is very interesting. Paul has a wide range of knowledge. Postgraduate entrance examination is not difficult. If we embark on this road, we must master some supporting application technologies, such as CAD drawing, remote control, field research ability and so on.
