If you go abroad to study mathematics-related majors, you don't need much effort, you can do it on the same day. There is no scholarship in the first year, and there must be a scholarship in the second year. If you are lucky, you should have more. Maybe you can have it in the second semester. There are quite a few people around me, Britain, America and Germany, which don't count as 20+20. . . . . GRE and TOEFL are very important, and the most important thing is your GPA. Personal statement is also very important (highlight your own advantages, is there any spirit that some Americans, especially schools, value). If a teacher is willing to give a good recommendation letter, the chances of scholarship will be much greater. So, have you won any special awards at school? Foreign countries attach great importance to universality, which is also a bit lucky. For example, Harvard University is short of football experts this year, and you happen to be good at football, which will lower your conditions. If you are excellent, but there are a few football players who are much worse than you, your place may be occupied by that football player. Then, there are many kinds of schools in America, such as Ivy League. This scholarship is not easy, but if you go in, you will basically get it. Then whether a state university or a private university has money will affect the probability of getting a scholarship. Then, you have to ask a few more times. There are many examples around you. The school said there was no scholarship. Tell me more. Of course, you have to be worthy of this scholarship, and then the school will give it.
