If you are a college student, you even took this major (that is to say, you can have a certain source of information-to put it bluntly, you can give some questions! ! This is the hidden rule of graduate students, although everyone knows it, but it is inevitable), so it is relatively simple to take an introduction to earth science.

But you have raised this question, and it is estimated that you are not a college student, or you have taken an examination of a non-original major (you can't get some questions).

So I think it's better for you to take the advanced math exam, because advanced math has no information for those students who take this major or our school. If you also take an introduction to earth science and the students who take the exam at the same time may have some information (after all, the school should take care of its own students, so it is easier if it is our major, and it is basically no problem to get any score, ...............), then your score difference of twenty or thirty (even forty) is not a dream. ...

Of course, if you choose advanced mathematics, you must do a long and boring study. Advanced mathematics is difficult, so we should review advanced mathematics from the time we start to review English. If your advanced mathematics foundation is not very good, it will be even more difficult. However, it is a very good choice for students who are admitted by other schools or non-majors (that is, people without any subject information sources).

In addition, you should consider your English situation when you take the exam. Half of the postgraduate entrance examination is about English, and English is also the most difficult part of postgraduate entrance examination. If it is difficult for you to pass the English exam, it is very wrong to ask you to take the advanced mathematics exam. So if your English is not very good, you should choose carefully. ...
