Abstract: At present, the transformation of advanced mathematical underachievers also becomes a difficult problem for the higher math teachers and their teaching. Take Yunnan Agricultural University as an example, based on the comprehensive analysis of the present situation of the higher mathematics education, the paper attributes the causes of mathematical underachievers to environmental factor, teacher factor and student own factor, and proposes some transformation strategies according to the different causes: improve the quality of teachers, to create a good learning environment for these students, develop mathematical thinking of them, stimulate their interest in learning, correct their attitude towards learning. Through the transformation of higher mathematical underachievers, the higher mathematics education can achieve a satisfactory result in agricultural colleges and universities
