Northwest University biology entrance exam is good. Biology itself is not a very popular major, so the competitive pressure is relatively small. Secondly, the examination subjects are cell biology and biochemistry, among which the reference book of cell biology is Zhai Zhonghe's fourth edition and biochemistry is two big green books. In terms of re-examination, there is no written examination for graduate students in Northwest University, which reduces the burden of re-examination for candidates. Discipline history: The Department of Biological Science and Technology of Northwest University was established in 1924, which is one of the earliest institutions of higher learning in China to establish biological disciplines. In 2000, it was named College of Life Sciences. In the past century, the Biology Department of Northwest University has trained outstanding biological talents, including Academician Yan Longfei, former director of Institute of Botany of Chinese Academy of Sciences Lu, former CEO of National Jieqing Ren Haiyun, Yuan Ming, Zhu, Kong Hongzhi and Huada Gene, which is an important base for training high-level life science and technology talents in Northwest China.
