United States:

Amherst University, Massachusetts, amherst;

Case western reserve university case;

Akron, university of akron;

Different schools and majors apply for different grades. LZ can refer to the volunteer reference system for studying abroad and enter majors. And you can find out the cases of classmates who are similar to you and see which colleges and majors they have applied for. You can also screen according to the goal of studying abroad to see what the background is (language achievement, school background, major, GPA, etc. Students from your target colleges and majors have applied, so compare your own situation and make general goals and directions.
