Compulsory majors require math scores, and general schools do not accept non-math unified exams to math unified exams!
Hurry and choose something else!
If you want to adjust now, I think it's too late! The average school is full around April 15! There is no school to transfer students now!
If you haven't succeeded, I suggest not waiting any longer! Looking for a job or fighting World War II!
Good luck!
